SPLASTiK said:The Rev A PowerMacs had Firewire problems I'm pretty sure. If I remember correctly it was only the ones on the front.
And the first gen iMac G5's had overheating problems causing the PSU's to fry I believe, also problems with hard drives, cheap capacitors and video problems.
Apple fixed this by replacing all the faulty ones free of charge.

And I remember problems with late 2004 models where the CD drive wouldn't open after 2 hours of using the computer, and the computer would freeze during video intensive useage. That was later fixed with updates.
I stand corrected. I've been very lucky with my Macs (knock on wood) over the years.
