I recently replaced the old standard, underpowered dell psu in one of these machines with a CX500--the system works like a charm with one exception: the screws on the back of the case don't line up with the screw holes in the psu. Consequently, the PSU jiggles around a bit. Is this a problem? How can I secure it more readily? Until I do so, I'm reluctant to leave the PSU turned on when I leave the house for fear of potential grounding issues that I've read about on other threads. Thanks!
