My daughter was handed down a 20" G5 which she really enjoyed. She called in tears that her G5 was dead. I said bring it over to the iMac Emergency Room. (My hobby room).
I got busy on my iMac contacting iFixit for parts and a repair guide.
Soon there was a knock on my door and a postman appeared with a package in hand. Just the right parts I needed. There was joy in my daughters computer room again.
I sure do appreciate iFixit being on line and available, with parts, manuals and advice. (I've also replaced a power supply on a G4 with iFixit help. It's still going strong.) I forgot to take pictures.
