My dremel job doesn't look too bad. This is a Coolermaster Wavemaster case and I am not sure why they had this backplate on the PSU holder, but I kindly removed it and the new PSU just barely fits! I can't beleive how hard it was to cut through the aluminum!!! I thought aluminum is supposed to cut like butter but I was mistaken I guess.
This is what the mainboard looks like mounted before it slides in the back:
Anyway, by tonight I'll have some 3dMark scores.
