Ok, maybe it's because I slept 1 hour in the last 38, but here we go. I know there are drive rails, and they rock cuz we use them at work. But i can't seem to squeeze the optical in (no sick jokes please) from the outside with the brackets on them because it's just a hair too wide.......do I have to yank out the power supply to install optical drives in the 5.25 bays? I thought about sliding it in from the front without the drive rails and just screwing them old fashion style, but the holes don't really line up. Someone please help me from my own apparent stupidity....thanks
