The cap should be common enough that he can find one at Radio Shack. I just upgraded my 20" CoreDuo iMac to a Core2Duo last week. It just so happens that the CoreDuo iMacs have socketed processors, which is unusual. Typically, they are soldered to the motherboard. $105 on eBay and an hour's work and I now had a Core2Duo 2.3GHz processor in my iMac. While I was inside it I took the opportunity to put in a larger (750GB) hard drive as well.
Unfortunately, the drive failed on Sunday, apparently from heat. I was able to see its SMART status before it completely cacked, and there were numerous high temp errors. Damn! I didn't even think about the additional heat load, which I could have avoided by using a utility to run the fans at a higher speed. Poop. However, all is not lost. While restoring the original hard drive, I found an EFI update someone had written that bumps my machine up to the next level, allowing it to recognize 4GB of RAM rather than just 2GB. The firmware for the CD machines will only allow them to recognize 2GB. So now I have an iMac that is probably good for another 5-6 years. Ain't technology grand?
