OK, I've been checking out various forums and help pages looking for information on how to take apart my G5 iMac to replace the UJ 846 optical drive. I have the iSight model which the Apple help page doesn't cover as to how to fix. I am lead to believe that the LCD screen must be removed to perform this task. Am I crazy to attempt this at home? Has anyone done this themselves? Any information would be welcome. Cheers, Phil.
