mining rig layout

I really like this mining rig layout, but how in the world would the risers connect to the mobo, most risers cables are only 60cm??

PSU cables might be too short too, whats the benefit of that design?

Benefit? Look at the GPU's, the fans are picking straight from the "air" not with GPU's in front of the fans

That sounds great when you dont have multiple rigs in the same room, i have a 7gpu 1060GB rig, they sit less than 2 inch from each other, no heat issues at all.

Yeah correct, if you got a good setup you shouldn't have a problem anyway.
