The computer itself was a work horse. The screen is beautiful and the machine worked incredibly well. It was fast and truly fun to look at.Right around the 16th month it died. I was working on it one night and the next morning it no longer powered on. I maintained this computer extremely well. Kept it under all the right conditions and had it connected to a great power conditioner and backup battery but it did not turn on. I troubleshooted with Apple and they recommended for me to take it in. The shop I took it in said it was beyond repair. RIP beautiful IMac
