Windows is installed along with gpu drivers and afterburner. The rigs are already clocked and tuned for optimum mining so you don't do anything to the rig other than plug in drive with nicehash OS and insert your wallet number.
2000w psu with power cord. Mining on Nicehash OS at 236mhs at 1150w and around 60 - 68 degrees per gpu dependent on conditions. I run them with the big fans off and the lid off for better circulation. If you have the lid on, you will need the big fans on too, simply plug them in inside the case. I have external drives with the NHOS installed, just input your own farm ID and away you go.
IMPORTANT: I have these in hand now, no waiting for GPU's to appear. The GPU's are 8gb not 4gb.The item "Crypto mining farm rig 8 x 8gb rx570" is in sale since Sunday, January 31, 2021.
