VERY nice, Kathy!! I'm sure you'll love the new iMac.
But Kathy...I don't think that "genius" was much of a genius!!!!!!

"Shortly after Apple Care expired my Power Mac G5 (Dual 2.7 GHz; early 2005) experienced various problems (e.g., non wake from sleep; sleep to run-away fan; loud fan; etc.). No coolant leak was initially observed.
After a loud "pop" and the smell of burnt components the G5 was "toast" (and coolant was clearly observed).
At a local Apple Store I was helped by a very efficient Apple 'Genius' and after consultation with his store manager I was informed that repairs would be completed at no cost. The repair invoice listed the following: Power supply, Logic Board H, Multiprocessor 2.7, and Hardware Repair Level-2.
Apple displayed laudatory customer service--thank you Apple!

With the symptoms you've experienced, it sounds like a leak...I'm assuming here that if you've had that machine for 5 years that it's one of the liquid cooled G5's?? (the only other 2.5GHz G5s were quad processors and came out in Oct. 2005) If it's one of the liquid cooled models, Apple is repairing those free of charge (or replacing them, as they did mine, if you're lucky) if your problems are due to leakage of the coolant. If it is now behaving itself, then fine - no problem. But if you continue to hear funny noises or have strange behavior consistent with logic board failure, I'd take it to the nearest Apple authorized repair shop and ask them to look for signs of leakage and tell them you suspect that there may be a problem. The leakage generally affects the logic board and sometimes the power supply. In my case Apple would have had to replace both ($1700) and the logic board was backordered according to my repair shop.
IF you do end up taking it in and they do find leakage, make sure that they are aware that this is something that Apple has been repairing at no charge even though these machines are out of warranty. When I took mine into the shop in November last year, they weren't aware that Apple was repairing them for free and I think the guy thought I was nuts when he said "I've got bad news - you've got a leak and need a new logic board" and I responded "Hallelujah!"
You'll probably need to get on the phone yourself once it's diagnosed - get an Apple case number and probably escalate it to second tier support unless the 1st level are now aware of the repair program. It's not an "official" repair program, btw - you won't find anything on Apple's web site about it. But you can certainly cite all the cases at xlr8yourmac.com and mine too, if you want to.
