That only applies to the revision a and b iMac G5s. Rev 3 (radeon x600 graphics) and intel imacs are much much much more difficult to get apart. that and chances are that the casing won't go back together as snugly as before. We're talking lots of tape, sharp thin metal, and winding cables.tvguru said:I don't know of a guide, but if you've done it on a pc before I'm sure you won't have a problem. I've had to install Airport cards into iMacs before and it just looks like a really nice pc inside. The hard drive looks fairly accessible but I wasn't looking at it that closely. Just open it up and have a look.
Take the computer and place is screen down on a towel or something soft on a table. Then unscrew 3 (pretty sure it's 3) screws on the bottom. Then you can lift the cover off by the stand. Bottom comes up first then off the "clips" at the top. Then you will be able to see how easy it is. Put it back together in the opposite way. Clips, bottom, screws.
