You should replace ALL the caps, with the same kind that are installed now. A capacitor can look good and be faulty, so don't go by looks alone, especially when dealing with iMac G5 and eMac G4 capacitors. There are a number of places online that sell cap sets, including eBay. Here's a good place to start: <http://jimwarholic.com/2008/07/how-to-repair-apple-imac-g5.php> I've successfully bought and installed capacitors from Jim Warholic as well as from eBay vendors. You're most likely to have success if the iMac still boots and runs, even if for only a few seconds -- in my experience. Dead as a doornail iMac G5s that don't chime and light up the screen most likely have suffered terminal damage to the logic board. (Been there, replaced all the caps, only to find the iMac was dead, dead, dead.)
