I have been trying to install a older DVD-RAM drive in the second bay of my Mac Pro. I've been able to get the drive installed and working, however the drive try will not clear the exterior door on the Mac Pro case. I feel like that if I removed the doors that the drives would work, but I cannot find any instruction on the removal of the doors. I could locate one screw on the access panel side, but something is holding the door assembly on the other side. Does anyone have information on removing this part?
