I have an Apple Imac G5, not the apple of my eye but a "lemon". It was purchased 18 months ago and we took out a warranty of 2 more years. In that time, within 18 days of owning it the machine was returned to Apple Care for a new logic board. Yes 18 days of purchase, they tried 3 new Logic boards and they were all duff ones, we got it back 2 weeks later, working okay then. Until a month ago when all locked up, returned once more for a new hard drive, none in Australia or Singapore 10 day wait, ugh! After receiving it back one evening it lasted 20 minutes, did a complete uninstall following Apple's directions and still no good. Collected again this last Monday and yesterday [Friday] we were informed another new hard drive was ordered and arrived yesterday to be installed on Monday. Wish that I had never seen the thing, be very careful what you wish for. So counting the original set up - that's, 4 logic boards and 3 hard drives in 18 months and all I do is research genealogy and surf a small amount of the web. Disappointed and getting angry although Apple have said that if it isn't fixed within 30 days they will replace the machine. Fed up in Adelaide!
