This looks really clean, nice.
for the old boys:
how do people actually mined with all those gpus on a single motherboard..? I mean, do you needed all the drivers or what? guide me through it.
Back then there was a lot of info on a few motherboards. The motherboards had in some cases 5-6 GPU slots (Even x1 slot's were used). We used risers to spread them apart and try to push air through them. Needless to say it was quite a different world.
