This is all without a case. Recommended to not put this all in a regular case, but to spread the GPUs out. I made some ghetto-fabulous case while my openrigs case arrives. The cards are about 5" apart and am getting <70*C in an open area (not even using a box fan). 1600+ khash/s and pulling 630-700w from the wall. Seems like a solid, efficient build if anyone was looking for some ideas.
