Less than one year old, work perfectly and mining for Ethereum as I type this. I have already minted over 24 Ethereum Coins with the four rigs!!! Each mining rig has 6 high end AMD Ratheon RX 580 AND the following components:
GREAT Hash rate, have been working flawlessly since professionally built. I have a total of FOUR Rigs to sell (each rig cost over $5,000.00) and this posting is for one of the complete, working, mining rigs or you can part it out to built a lightning fast gaming PC. If you are interested in more than one, discounts would be provided.
This unit is PLUG and PLAY, literally mining right now.
