iMac has been Apple's lineup of all-in-one computers since 1998. Each of these models has their own problems, but they are very fun machines to own.

Common iMac G3 issues include speaker rot, optical drive issues, flyback failure, and yellowed/brittle plastics.

Common iMac G4 issues include issues with the screen hinge becoming loose, although this is rare.

Common iMac G5 issues mainly include motherboard failure due to failing electrolytic capacitors.
