I had like 3 friends ask me how to build a PC in the past week so I made this to help them.

(Reddit Edit: Help my improve the document with productive constructive comments on what I got wrong or messed up! Im only human lol
Also a lot of this is supposed to be kinda humorous. I didn't think I had to say that but, hey, its the internet.
I appreciate the positive and productive comments! )
Beginners basic guide to building your own PC as of early 2018
(EDIT: Sorry for being a MSI/Corsair Fanboy)
Heres a collection of thoughts to consider when building your own personal PC
As always Id personally use PCPartPicker.com to configure your parts and for further thoughts on compatibility.
First off building a computer is 100% based around what you plan to use the computer for.
Here are a few uses and generic ideas of what to go for. Audio Editing: Lots of small tasks that need to be completed quickly without lag. - Fast Processor( >4GHZ) - Fast RAM (MHZ) -At least 16 gigs! - Fast Storage, SSD manditorily - M.2 or PCI for best performance. - Shitty Graphics card, graphics card there only to keep the cpu from doing other tasks when working. - Can be a few generations or years old. - Many screens for lots of plug in windows to be open Video Editing: Lots of large to render and files to read. - Multi core processor the more the merrier - SSD for fast read/write of large video files. - Insane graphics card, AMD graphics cards are debatibly better but the nvidia Quadro series are specific for video rendering. Gaming: No more than 4 cores intense graphics card - 92% of games are not coded for more than 4 cores so why spend the extra money for it. - SSD for quick load screens - Nvidia cards, 10 series, the higher the number the better. Titan cards for MAXIMUM OVERDRIVE! Coding: quick processor for lots of small tasks. Ergonomic peripherials? - Dear god please dont use a mechanical keyboard so that your coworkers dont kill you. Home office: Everything can be a few gens behind so you can get the best power per dollar spent. - Sorry that Gateway doesnt exist anymore. I guess try Dell... 
Parts (Expensive Legos)
CPU (tells things to go places and outputs data) Basically three main routes to go for: Intel, AMD, or ASIC. Intel - Gaming, Data center, Hackintosh Pros: Cooler, Faster speed (GHZ), short small tasks faster Cons: $$$$, less cores AMD - Gaming, Personal Computing, Large task processing Pros: Lots of cores, better price per performance, faster processing of large tasks Cons: Hot chips, large chips?, compatibility issues with MacOS. ASIC - "Application-specific integrated circuit" Pros: Does the task that they are made to do insanely efficently, great for mining. Cons: Literally does nothing else. Holy hell these are expensive, very hot (fans will get loud) CPU Cooler (Im a big fan) Most come with an in box cooler that are ok but please buy aftermarket. In Box - the free shitty cooler that comes with the processor. Pros: Free. Cons: Ugly, makes chip run hot, hard to clean Air cooler - oldest type of cooler but new designs are highly efficent. Pros: Only cooler that has the possibility of being 100% quiet, most likely cheaper Cons: large, if cooler isnt large enough for the chips thermal output the fans will be loud. Liquid - Custom pipes are beautiful, AIO is easy to install and offers similare performance. Pros: Looks cool, great temperatures, "quiet" Cons: Water pump has possibility of being loud, possible spills Phase Change - uses the technology of refridgerators to cool the chip Pros: Can overclock until the chip breaks. (whats colder than cold? ICE COLD!) Cons: Loud (compressor noise), Large pipes, just why.... Motherboard (the convienacnce store of computer parts) Really just about what type of I/O you want. - MAKE SURE FORM FACTOR FITS YOUR CASE!

If the straw is wider you can drink more of the milkshake than a skinny straw. - Faster MHZ for faster data access but give minimal performance differances - Please get ram with heat spreadders unles youre building a server with high airflow. - Make sure the type (DDR3 or DDR4) of RAM matches what your processomotherboard call for. Good Brands: Corsair, G.Skill, Ballistix Storage (Grandpa that remembers everythign about how things used to be but takes forever to learn a new tasK) Speed or massive storage? slower is cheaper. Golden ratio of speed/storage/price is 250-500 gb SSD and a 1+ tb disk drive. *Max speeds listed are for a single drive not RAID* Hard Disk Drives (HDD) - Cheapest and slowest - read/write speeds of < 0.5gb/s - 7200+ RPM or GTFO - Higher Speed drives can access data faster. - Do not move while powered up. physical parts will break. - Larger Cahche = faster Read/Write Speeds Pros: Cheap, Holds massive amounts of data Cons: Slower than molasses in a frezer Reputible Brands: Seagate, WD Solid State Drives (SSD) - necessity for quick boots and fast load screens (can only be re-written to so many times) - SATA based (2.5 inch)- Read/Write speeds capped @ 6 gb/s Pros: Most economical, form factor fits with old computers, Cons: "Slow" compared to other ssd's (but stil 12 times faster than a HDD) - M.2 based - Read/Write speeds capped @ 10 gb/s Pros: Size of a sick of gum! High End but not too expensive to be out of reach. Cons: Expensive for any size over 500 gb - PCI based - Read/Write speeds capped @ 20 gb/s for PCI3, x4 Pros: HOLY BANDWIDTH BATMAN!

[USA-ME] [H] Gridseed (Scrypt), Antminer U2 (Bitcoin) USB ASIC miners [W] Paypal

http://imgur.com/a/Q1EV0
Perfect for learning about how ASIC mining works, or just playing with bitcoin/litecoin/dogecoin mining. Just a note that these devices are working but I can't really offer support on them, but are being sold as working properly.. anyway. Prices shipped in US.
2 1 Gridseed - $30 each One without fan is available.
Antminer U2 - $40 sold
The two gridseeds (one has a fan installed, other does not) are technically dual purpose. You can mine LTC or BTC with it. I only did LTC which is low power (6 watts). Run around 330 Kh/s LTC. I didn't use the BTC but i believe those run at about 6 Gh/s in bitcoin mode. But then they end up using about 60 watts a piece. Fan isn't really needed running in LTC mode. BTC mode it gets a bit hotter and would need the fan. Includes a little 12v wall wart for each and USB cable.
The USB Antminer U2 runs at about 2 Gh/S running off of USB power.

For ASIC designers:Has bitcoin processing innovation with ASICs driven any processor innovation with other possible uses? Not the specific design probably but any other innovations?

Wall street robo trading has driven microsecond fiber speed improvements as well as whole new fiber cables being laid . I suspect Bitcoin mining hash/watt processing profit advantage will be driving some innovations too if it hasnt already.
Did usb ASICs exist before for example?

Raspberry Pi + ASIC defcoin mining guide

Want to get started mining defcoin with an ASIC and a Raspberry Pi? Does 360 KH/s of mining power sound appealing? Here’s how to do it.
https://pbs.twimg.com/media/Blpj8IvCcAEIStY.jpg
1) Hardware List
-Raspberry Pi Model B
--SD Card
--Micro USB power supply
--Ethernet cable
-Gridseed ASIC
--12V power supply (5.5mm/2.5mm barrel connector)
--USB to Mini USB data cable
The main component is the Gridseed ASIC, which will be doing the Scrypt calculations. The Raspberry Pi will be used as the controller for the ASIC, and will be doing the communication with the mining pool. If you’re not familiar with the term, an ASIC is an Application-Specific Integrated Circuit - basically a chip with a single purpose, like mining crypto currency. Using an ASIC will allow us to mine more efficiently than we would be able to with general purpose hardware.
The ASIC that I’m using is a “300+ KH/s Single Gridseed ASIC Miner”. It looks like a CPU heatsink with a fan attached. There is actually a circuit board with 5 ASIC chips sandwiched between two halves of this heatsink, and has a mini USB connector and a power connector sticking out the side. There are a few places where you can buy these. I bought mine at GAWMiners.com for $130. That was the lowest price that I could find, and I had a good experience buying from them. Use this link, and you can get $20 off of a $200 order (and give me some referral points :-)) GAWMiners. You can also find other vendors by searching for “Gridseed ASIC”. You’ll need a 12V power supply to power the ASIC, and a USB A to USB Mini B cable to connect the ASIC to the Raspberry Pi. I’m using a 60W power supply, which seems to be working fine for defcoin (Scrypt) mining. These ASICs can also mine Bitcoin at the same time, but you may need a beefier power supply if you want to do that.
The Raspberry Pi can be purchased at any number of places- Amazon, SparkFun, AdaFruit, etc. I’m using the Model B because I had one already, and also because it has a built in ethernet port that will make connecting to the internet easy. Make sure to get an SD Card and a micro USB power adapter to get the Pi up and running too.
2) Software
If you haven’t already, download the defcoin wallet from defcoin.org. If you want to do pooled mining, create an account for one of the defcoin pools, such as redbaron.us or whichever other pool you want to mine. Once you’ve created a pool account, make sure to create a worker too (for MPOS pools, that will be under My Account > My Workers). The password for your worker does not have to be the same as the password for your pool account (and it probably shouldn’t be).
Next, download the latest Raspbian image from raspberrypi.org/downloads/ and install the image to your SD card. Instructions for installing the image can be found here. If you are using the dd method on a Mac, make sure to use /dev/rdiskX instead of /dev/diskX - both will work, but rdiskX is much faster. Once you have the image installed, put the SD card in the Raspberry Pi, connect the Pi to your network, and connect the Pi to your micro USB power adapter to power it on. Next, SSH in to your Raspberry Pi with the default username and password pi/raspberry. I use nMap to find the IP address that has been assigned to my Pi. You can also use an HDMI display and a USB keyboard to log in instead of using SSH. After logging in for the first time, run through the wizard that comes up to configure your Raspberry Pi. The defaults are fine for most things, just make sure that you don’t skip the step to expand the filesystem to use the rest of your SD card. If you don’t expand the filesystem, there won’t be enough space for other software.
Once you have Raspbian installed, and have gotten through all of the first login setup stuff (which will likely end with a reboot), log back in to the Raspberry Pi with the pi user. From the command line, run sudo apt-get update sudo apt-get dist-upgrade
There are some stability issues with USB communication between the Raspberry Pi and the Gridseed ASIC. Enabling SLUB debugging seems to resolve this, at least well enough to prevent the Raspberry Pi from freezing every so often. Open the /boot/cmdline.txt file, and add the following text to the end of the line. Don’t add a new line, just add this to the end. You can use vi, nano, or whatever your favorite text editor is to do this.
slub_debug=FP 
Reboot the Raspberry Pi once you’ve added that flag to your /boot/cmdline.txt file.
sudo shutdown -r now 
Log back in with the pi user once the Raspberry Pi is finished rebooting.
The mining software that we’re going to use is a customized version of cgminer that has support for the Gridseed GC3355 chips that are used in our ASIC. There are a number of different mining programs out there, this is just what has been working the best for me so far. First, install git and dependencies needed to compile cgminer.
sudo apt-get install git build-essential libtool libcurl4-openssl-dev libncurses5-dev libudev-dev autoconf automake 
Next, clone the git repository for cgminer-gc3355
git clone https://github.com/dtbartle/cgminer-gc3355.git 
Next, we’ll build cgminer.
cd cgminer-gc3355 autoreconf -i ./configure --enable-scrypt --enable-gridseed make 
Once the make command finishes, we’re ready to run the mining software. You can also run make install if you want to install the software, but running it out of the build directory works just fine. Plug in the power supply for your ASIC, and connect the ASIC to it. Connect the USB cable to the ASIC and to your Raspberry Pi. Run the mining software by running the following command. The -o option specifies your pool URL, the -u option specifies your username and the workername that you set up for the pool, and the -p option is the password for your worker. There are a couple of options available that are specific to the gridseed ASICs, and those will be placed after --gridseed-options. The freq=850 option sets the clock frequency of the ASIC to 850 MHz. There are other clock options available, but 850 seems to be working best for me. I was getting hardware errors at 900, and a lower average hash rate. I am getting about 360 KH/s with the clock frequency set to 850.
sudo ./cgminer -o stratum+tcp://www.redbaron.us:3333 -u Username.Workername -p yourworkerpassword --gridseed-options freq=850 
This command needs to be run with sudo in order to access the USB hardware. You can also create another user specifically for mining, or grant the pi user the appropriate permissions if you don’t want to run cgminer as root. When you run this command, you should see output from cgminer showing that it is communicating with the mining pool, and something showing your hash rate. If you’ve gotten this far, and you’re seeing output from cgminer showing a hash rate, congratulations, you’re mining defcoins with your ASIC! There are just a couple more steps to do if you want to let your Raspberry Pi and ASIC continue mining without needing you to be logged in.
To keep cgminer running after I log out, I am using nohup. You could also use screen instead of nohup. Create a script (startMiner.sh) by running the following commands.
echo “nohup /home/pi/cgminer-gc3355/cgminer --real-quiet -o stratum+tcp://www.redbaron.us:3333 -u Username.Workername -p yourworkerpassword --gridseed-options freq=850 &” > /home/pi/startMiner.sh chmod a+x /home/pi/startMiner.sh 
If you run this command with sudo startMiner.sh, cgminer will run in the background, and will continue running after you log out. If you want to have this run when your Raspberry Pi boots, modify your /etc/rc.local script so that it executes this startMiner.sh script. Your /etc/rc.local file will end up looking like this:
# Print the IP address _IP=$(hostname -I) || true if [ "$_IP" ]; then printf "My IP address is %s\n" "$_IP" fi /home/pi/startMiner.sh exit 0 
That’s it! You should now have a Raspberry Pi controlling a defcoin mining ASIC, that starts mining as soon as it boots up. For more reading, check out some of the links below.

Crypto mania is taking the world by storm! From reaching a combined $600 billion market cap, to Bitcoin trading at $20k on some exchanges, there seems to be no stopping the rise of digital currencies.
There are many ways to cash in on the potential that crypto has to offer, one of them being mining. This is the process where each transaction or record on the blockchain network is verified. As a reward for their contribution to the network, the miners receive freshly generated cryptocoins.
The cryptocurrency mining process is extremely processor as well as power intensive, and can get expensive if tried individually at home. Not to mention, the mining process requires specialized hardware, which has to be set up by oneself along with the power supply to feed the hardware. Genesis Mining steps in here to make the whole process easier, allowing interested cryptocurrency community members to be part of the mining community without going through any of these hassles. On a mission to “democratize mining”, the company is providing accessible and affordable cryptocurrency mining solution to the masses.
Genesis Mining provides cloud-based mining services to small- and large-scale investors. Their mining farms already have all of the equipment set up. In fact, the platform has the best Bitcoin and Altcoin-mining hardware and software available and running already.
The representatives of Genesis Mining have recently taken an initiative through their “EvolveWithUs” campaign to explain cryptocurrency mining and their services in the sector to the general public to increase awareness about the process and the company’s offering.
What is a Mining Rig?
Stefan Schindler, CTO representing Genesis Mining offers a simple definition for the most crucial hardware in the mining operation by saying,
“A mining rig is basically a computer, but is stripped down to the minimum in terms of computing, and up to the maximum in terms of mining.”
The Evolution of Mining
Mining had previously been done on a computer’s processor. However, as the industry grew, so did its mining requirements. Processor mining took an enormous amount of power, and an alternative was eventually adopted — Graphic cards. Graphics Cards or GPUs, proved to be more efficient at processing transactions, and didn’t use nearly as much power, resulting in a classic ‘work smarter, not harder’ approach. Since then the industry has advanced, creating specialized hardware called ASIC miners. However, GPUs still play a vital role in mining some of the popular alternative cryptocurrencies (Altcoins) in the market.
The Structure of a Mining Rig
In appearance, it looks like your average computer mainboard. The key difference is that is filled with lots of GPUs. The USB port contains USBs holding the actual mining software, which is not stored on the processor. It also has plenty of connecting cables to make everything run.
GPU processing
In the case of Genesis Mining, their specialized mining rigs can hold about six GPUs each. The mainboards available on the market do not have the internal space or slots for all of these GPUs that goes into Genesis Mining’s version of mining hardware. This is where PCI risers come in, which are extension cables that allow the mainboard to be fitted with many GPUs. These risers also help with even heat distribution so that the rig doesn’t overheat.
The power supply unit is also fitted with a strong cable, and powers all of the GPUs and the mainboard.
The company manufactures, stores and operates the mining rings at their mining farms in Iceland and other locations. These equipment can be quickly and efficiently assembled and are completely mobile for added convenience.

Building a Dual Rig (gaming and mining)

What is your intended use for this build? The more details the better.
I’d like to build a gaming/mining rig. I would like to run 6 graphics cards at one point, might not buy them all outright. So the goal. A gaming computer running the 1070 separately so I can still game and do stuff while the other 5 cards are mining. When im not using the computer, I have the option to put the 1070 to work as well. Is it a stupid idea to combine the two purposes into one super computer? Also, I’m having trouble finding a compatible motherboard and would love suggestions. Finally, I have tried reading on the riser connection info and I’m still not sure. Hopefully those are the correct risers?
If gaming, what kind of performance are you looking for? (Screen resolution, framerate, game settings)
Nothing too crazy. I have done the research on that side of things and the things selected should make me happy.
What is your budget (ballpark is okay)?
$2000-3000 (depending on how many gpu’s I buy at onece)
In what country are you purchasing your parts?
U.S.A (amazon, here is the link my current list. https://www.amazon.com/gp/registry/wishlist/2NAC9YOHISTRI/ref=nav_wishlist_lists_4)
Post a draft of your potential build here (specific parts please). Consider formatting your parts list. Don't ask to be spoonfed a build (read the rules!).
CPU:
AMD Ryzen 5 1600 Processor with Wraith Spire Cooler
Motherboard:
Im not sure!
Memory:
Corsair - Vengeance LPX 16GB (2 x 8GB) DDR4-3000

Help with getting things to start mining scrypt currencies (using raspberry pi 2 , gridseed asic miner , & cgminer) . . .

Here's what I have & will be using (I already have the cables & power) :
raspberry pi 2 Gridseed ASIC Miner for Litecoin and Bitcoin Mining --- 4 of these cgminer
[ I followed this example for setting things up : https://www.reddit.com/defcoin/comments/23nvs1/raspberry_pi_asic_defcoin_mining_guide/ it is my understanding that any altcoin you wish to setup mining for , is done in this similar fashion ]
I want to do scrypt cryptocurrency mining , I just want to understand how this is done ....
( I know there's a lot of tutorials out there & great vids , and I've done a lot of reading on all this matter , but I can't seem to get things working right , please help / advise )
Questions:
  1. if I solo mine , what is the correct port # to use here (and is the below command formatted correctly more-or-less) :
sudo ./cgminer -o stratum+tcp:localhost:#### -u Username.Workername -p yourworkerpassword --gridseed-options freq=850
( I understand I need to create my own pool , a pool of 1 , is considered to be solo-mining , correct ? How do I do this ? )
  1. also , before I can solo-mine , I need to have downloaded & install the wallet for the cryptocurrency I am going to mine , correct ? And I understand there is some kind of Config files relevant that I should modify accordingly to set things up with my mining solo , right ? How is it done & where do I find this config files ??
  2. I tried connecting my 4 gridseed(s) to my raspberry pi 2 , via the 4 usb ports it has , but it seems like it can't handle the 4 of them , so I have to deal with only using 2 of the gridseed(s) connected to my raspberry pi 2 at a time .... does this seem right to you ? And so , what work around do I have for this poroblem , I want to use all 4 of these gridseeds connected to my raspberry pi 2 ,,, I'm guess a usb hub is needed for this right ?
THANKS IN ADVANCE FOR YOUR HELP AND GUIDANCE !!!

[CANADA-BC] [H] Crypto Currency Mining Enclosure and hardware FULL setup sale [W] $ or Bitcoin

I own a crypto currency mining investment company and I'm selling off the current hardware setup. It has been in use since mid-March of 2014. I've had a series of unfortunate events occur in my personal life that require me to sell off my business's hardware and other personal items.
This is for a firm priced sale, I am looking for a buyer that is either wanting to get into the mining business and wants a GPU based setup that can tackle all the new algorithms VS ASIC based setups that go obsolete within months and have no resale value. Or a buyer that wants to expand their mining farm or mining business and would love a plug-n-play type setup where the only thing they are required to do is have one power feed wired into their warehouse or home panel. This would be for local pickup only most likely. It will require the buyer to have a truck or to rent a u-haul type of moving truck. The system is roughly 60 inches tall by 95 inches long by 24 inches wide, not sure on its weight but moveable if the cards are removed(the cards are designed to be plug-n-play as well, no screws, just pop out pop in.) and runs at 240v for PC hardware and 120v for fans/misc regular appliance plugins(routers/switches etc).
The enclosure houses 8 systems which consist of 46 R9 280x video cards (it has room for expansion), has its own built in surge protection system to withstand lightning and other outside-the-enclosure based surges, whole system runs at 240v for best efficiency, has a 100amp breaker panel which is attached to the enclosure for maximum expansion.
The enclosure has 6x20 inch box fans which provide the 24/7 constant air flow for the video cards. I have two other 20 inch box fans that are for in and out airflow for fresh air circulation. All video cards are easy to access and can easily add or remove cards to/from the unit. I built the enclosure design in-house.
Serious inquiries ONLY, I have priced this as fair market price for used hardware among the enclosure costs which include the power panel, surge protection, cable runs, professional electrical hardware/electrician fees etc. This is a full plug and play type enclosure setup for any mining farm out there. Originally built for $33000~, I'm strictly selling it at a fair hardware priced value with cutting out a lot of the fee's that you would have to pay for an electrician to wire up your own custom enclosure and the electrical hardware. Cash or Bitcoins only.
Asking $15000 Canadian firm. Also I am located around Vancouver, British Columbia, Canada.

Dr Jally or: How I learned to stop worrying and love the ASIC.

I was a late comer to the bitcoin love, I started mining last summer, nothing major, have never had more than 600Mh/s to my name really... but on a whim I ordered a Jalapeno in late august, and then I tried to put it out of my mind as everyone else fought over if BFL would ever ship or not, etc.... I just figured that worst case, the money was gone really... lo and behold, it arrived about 3 weeks ago, let me briefly share a few things, as some of my tinkering and experiments may benefit others:
This past weekend I opened the little black box of mystery and had some fun:
I plugged everything back in, powered up my host... and noticed my jally was just flashing like crazy and my host couldn't see it. uh-oh. I powered it off, back on, and it was fine. Since then I've powered it off about 10-20 times, and twice it would go into "super fast flash like crazy but not work" mode. Simply unplugging and replugging would solve it. I have not dug into this at all, but I think it's failing to init or pass the boot up tests. There's word around town that you can tweak the firmware to push speed further or reduce the strictness of the tests it does, but I'm happy with what I've got, so I'm leaving it:
Right now
Other than to change coins or work on my host system (now that it's a raspberry pi I don't think I'll be changing it much more), it's been running non-stop at around that rate/temp since the weekend.
Right now my little rPi host is bashing away, with the jally and three block erupters (I know they'll most likely never reach ROI for themselves by themselves, I just wanted to tinker, but still may add a couple more to break 10Gh total just for bonus points), the jally firmware "upgrade" everyone talks about is really designed for one of the other models (the bigger ones), and that's why I think it reports as "BFL 0h" or "BFL 0d" I assume "d" and "h" are the two ASIC spots on the jally board that actually have chips on them in the jally...
I figure all in I'm looking at around... lets say $650 and 90 watts (max) total for ~8.29Gh/s... The erupters really distort my numbers right now, (without them it'd be more like $350 and 80 watts (max) for ~7.3Gh/s)... but again, hashrate is addictive.
The jally power supply has always seemed to run hot to me, even before I pushed the update firmware, so I may try and find a biggebetter quality PS for it, and more erupters will sadly mean I need a new usb hub, as my current one is only rated for 5v 2A, and it has to be close to that with 3 erupters, the pi, and the usb fan. :/ So I guess I've still got more investment to go, but it's just a hobby, I can quit anytime, right?
right?
tl;dr edition (or what I learned, without the story):

[WTS] 23.5 GH Mining Rig

At the moment I'm fielding offers for the entire mining rig.
I will not be parting this out and will be selling at as one entire unit. I will pay for shipping. US only.
Miners
Equipment
Current setup allows for 12 in each internal USB hub, 5 in each 7 port hub a max recommended of 9 for the two 10 port hubs. You can try pushing it with 1 more in each of the 13 porters and 1 more in each of the 7 port hubs but it isn't recommended. Based on that, there is room for 4 more usb miners recommended setup, and 8 if you want to push it.
http://imgur.com/a/Rm5pf
Please post an offer below. Going by current prices I'm looking for 8+ BTC. (Miners and Jalapeno alone at current prices around 7.8 BTC, .1 BTC per USB Miner and about 3 BTC (per ebay) for the Jalapeno) I know I won't be getting back what I paid for, but these are quality hubs and power supplies.
I've also put this on Ebay http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=281182502521, but I would prefer to sell it for Bitcoin.

[For Sale] Butterfly Labs 5 GH/s Jalapeño ASIC Bitcoin Miner - runs at ~6.7 to 7.3 GH/s stable

I want to sell: Butterfly Labs 5 GH/s Jalapeño ASIC Bitcoin Miner
The price in BTC (includes shipping): 1 BTC to 134Z2Sv5B7UwUhoSxypaXGyjqHKWoTWUgv
I am willing to ship to: USA (others negotiable and not for free)
Images of my product: http://imgur.com/a/EcgZh
Proof of hardware and hash rate in images linked above. Note that trail off at end of graphs is from shutting down the miner purposefully.
I am the first owner, and I received this miner directly from Butterfly Labs less than 48 hours ago. I still have the original box, power supply, USB cable, and of course the miner.
After tinkering with it for a few hours I have successfully mined Bitcoins (BTC), Freicoin (FRC), and Zetacoin (ZET) using my MacBook Pro and the miner GUI Asteroid. Pretty cool stuff. I have a few fractions of BTC in my wallet now so I can say that, "I mined cryptocurrencies back when I was your age" to the grandkids one day.
Now that my curiosity is sated, I'd like to pass this ASIC on to another aspiring minetinkeregeek and let them have a go at it. I can offer help if you are running Mac OS X.
If you are in the Seattle, WA area I'll deliver in person and help you get it up and running.
