I'm stuck with what I thought was going to be an easy job - compared to a G5 tower or an iMac. I need to replace the power supply in my Mac Pro (2008) but I'm stuck at getting the small cover off. I've removed the metal plate that was under the optical drives (POV when looking through the side). But it seems there's a small cover for the power supply that's similar to the big processor cover for the liquid cooled G5 towers. I can't figure out how to remove that. Does anyone have a link to a manual or take-apart guide for the Mac Pro? Thanks!
