This has probably got to be the easiest and most efficient way to get air out. It also greatly reduced the noise level since the holes have been chopped out.

   I had a spare YS Tech that I ripped out of a Globalwin hs/fan combo so I decided to stick it in the space next to the I/O panel right above my Geforce. Since I had my Alpha heatsink fans suck air out, there was a tremendous amount of hot air sitting right on top of my Geforce. The video card itself was pumping out heat also so this was a good way to get rid of some air at the hottest spot. I penciled, taped and drilled. I had a couple of mistakes because this panel for some reason was very stubborn. Maybe it was because I was getting very impatient and wanted to get the damn thing over with :) :
