This rig has been consistently mining Ethereum since April.  It's compact and has room to expand to more GPUs.  Here are the specs:

Power Supplys - Montech Century 850W 80 Plus Gold and EVGA Supernova 850 Gold (Both currently running 110V) Average system usage is 640 Watts total, 5.6 Amps (110V)
PCIe Risers - PCI-E Express 1x To 16x Extender Riser Card USB 3.0 V009S (4 being used on rig, 4 extra) I've never had one fail.
Fans - 4 110mm fans are included, however I haven't used them. I've been using an external box fan to assist cooling.  One fan was delivered with a cracked frame, but is still works fine.
The rig is currently using AMD Radeon Adrenaline drivers and GPU control software and will continue to run until the end of the auction.  I use TeamRedMiner for mining software, however, there are multiple options currently installed.
The rig will be shipped mostly assembled.  GPUs will be removed from the rig and shipped in separate packaging.  I'll label GPU wiring prior to GPU removal to assist with re-installation.  Install GPUs, update the batch file with your eth wallet and you'll be ready to mine.  I'll assist with getting it up and running if needed.
Due to the ever-changing crypto mining market, all sales are final and no returns will be accepted. Thank you for viewing and good luck.
