If you have not yet read our Introduction to Ethereum please do so.

We are selling computers in 4 different levels.  Please do the math to figure possible returns.

  • BasicBASIC – We have a limited supply of basic used computers that can have enough cooling and power to run a good video card that puts out 13-14MH.  We will guarantee 12MH.   It comes with 4GB RAM and a 160GB Hard Drive, on a nice Core2Duo CPU.  This comes in a nice, heavy duty, metal case with handles.  They use about 220W while mining.  These sell for $450 each.
  • MidMID – These are bigger computers, with better power supplies capable of doing 18-21 MH.  We will guarantee 18MH.   They also come with 4GB RAM and 160GB Hard Drives.  This computer is perfect for office and business use, you can use it while mining with no negative effect on mining speed.  The MID uses about 280W of power.  These sell for $650
  • DoubleDOUBLE – This computer comes with a much better PSU and two of the video cards that the Mid Computer has giving it 36-42 MH.  We will guarantee 35 MH.   These come with 4GB of RAM and a 250GB Hard Drive. The Double uses about 440W of Power.  These sell for $950 each. (This is our most popular model.)
  • TripleTRIPLE – This computer has an upgraded PSU, and video cards that push even more MH.  It gets between 54 and 63 MH, we will guarantee 50 MH.  This comes with 4GB of RAM and a 250GB Hard Drive.  The Triple uses about 610W of Power.  These sell for $1295.   As of June 1st these would return $270 per month, giving you all of your investment back in about 5 months.

There are video cards that can produce more, but they are not as cost effective as the cards that we use.  Also there are motherboards that can take up to 6 cards, but we have found that this becomes unstable, is hard to mount in the case and requires too much power from the PSU.  It is more cost effective to build 2 triples than a single 6 card rig.  Our rig designs are the most cost effective way to build these mining rigs at this time and scale.  We build all of these computers with power supplies that are much stronger than required.

All of our Miners make great computers also.  You can use them for office work or even gaming.  We put decent dual core or better CPUs in all of our machines.  To make any of these computers into a user computer we suggest upgrading the RAM to 8GB, which costs only $30.  Also you can get a 250GB HD for just $10 more, 500GB for just $25 more, or 1TB for just $45 more.  For more speed on your computer we highly suggest getting a SSD Drive, 240GB would add just $85 to any system.  You can use your computer for anything you like while mining, but to get a good gaming experience we suggest that you turn off mining while you game.

We are also able to make custom high end shelf based systems.  These systems can have any number of cards.  If you are interested in getting one of these systems please contact us.  We will be willing to travel to you to set it up, for a nominal fee.

Our guarantee.

We will test each computer, actively mining for at least a day before we ship it, during this test we will use your account data if you provide it so that you will be able to watch the test.  We are confident in the computer that you are buying, in the rare case of your computer does not performing as expected, as shown on public pool data we will log in remotely and try to tweak it so that it does perform, if it still does not perform as we guarantee, we will either replace it or have one of our computers mine for you to make up the missing mining power.  All of our computers come with a 1 year warranty against hardware defects.  If you have a hardware problem we will fix it or replace it during this time.


Shipping is not included in our pricing.  We are proudly located in Arizona in the US, computers will be shipped from our location.  You will be charge the actual rate that we pay to ups.  We will contact you once your computers are ready.  If you have your own shipping company or would like to pick up your computers in person we will be happy to call you when they are done and arrange this with you.  If you order 10 or more systems then freight shipping is often lower priced.  We will get a quote for shipping if this is the case.  We never mark up shipping.

If you are not in the US you will be responsible for any duties that your nation may impose.

There is no limit to the number of computers that you can order.  Be aware that our staff can currently produce about 20 units per day, so if you order a large number of systems you could be in the que for a few days.  After we build the systems we do a live test for at least 1 day, if there are any mishaps we do the test a second time.   Currently our delay from order to shipment is about 6-9 business days.  If we receive a flood orders we will ramp up production to meet demand but there could be a small delay during that time.

During the launch we are only taking BTC for payment of online purchases.  If you want to pay with a different method please contact us.
