Here's another site with a wealth of information about replacing iMac G5 capacitors on the logic board as well as the power supply, plus kits are available for purchase. I've replaced caps on dozens of iMac G5 and eMac G4 logic boards, and in a dozen or so iMac G5 power supplies. I started out replacing all of them, but I've come around to where I now replace only those with bulging tops or with bulging/leaking tops or that are tilted noticeably because the bottom rubber plug has blown (rare). My success rate of revival has increased dramatically since I started replacing only the observable "bad" ones. This is most likely due to the fact that it's extremely difficult to remove and replace caps on iMac G5s without damaging the internal traces in the layers of the logic boards, or failing to adequately melt the high-temp solder used by Apple and thus effect a good solder bond. Even after I've succeeded in reviving some iMac G5s, I have to go back and resolder a few joints that have come loose after a number of heat up/cool down cycles. If you're a glutton for punishment, go for the recaps. But be prepared to never completely trust that iMac again. On the other hand, I've have no failures of any eMacs whose capacitors I've replaced.
