[QUOTE="MacGuyFrom1831, post: 1817189, member: 401707"] [B][U]Starting on the newer iMac[/U][/B] I've dissembled the newer iMac and to my undesirable surprise someone had opened it prior to me. Fixing something someone else messed up is never fun, but fixing things only touched by the factory is always preferable. This is not the worst issue at this stage.
