Hey there,

I am interested in setting up around 50 rigs.
Now i have a good friend who is really into mining himself and has a couple of machines running aswell.
Unfortunately he has no knowledge of linux and i was planning to run the maximum amount of gpus on one machine as possible, to maximize profits
The gpus i am thinking about are the 7970, they are easy to get and have a decent ratio.
But to get back on topic, i don't have linux knowledge either. Is it hard to set up a rig with 6+ gpus without prior knowledge of linux?

Lets get to the hardware aspect. I was thinking about an open frame. That can hold 6+ gpus (and since it are 7970's i would need two 1200 watt power supplies? or would 2x 1000 watt also suffice?)
Further I will need components that are easy to obtain (making it uniform makes it lots easier to maintain). I have seen motherboards with 6 or 7 pci-e 16 slots, but i noticed all pci-e slots can be used?
So, anyone knows a motherboard with 6+ pci-e slots thats easy to obtain and of good quality? (maybe even 8 slots?)

also which 7970 would you guys advice? i was thinking about the one from sapphire, but maybe you people know something better?

thxn for the help

edit:
I just noticed there are FPGAs that run on very little electricity but deliver great Mhash. Is it better to get those?
