Richard, Here's the Jim Warholic site:
<http://jimwarholic.com/2008/07/how-to-repair-apple-imac-g5.php> Preventative? Hmmm. Take off the back cover, remove and clean out the top two fans and any other dust you see. Remove the mid-plane (see Apple's own DIY guides for this at www.apple.com) and clean out the dust from the cpu/gpu "G5"-marked air duct. Then clean out the dust from the bottom fan that feeds into the duct. Look at all capacitors on the logic board. Note how many are bulging and/or leaking electrolyte. See Warholic's site for copious information on this subject. Remove and disassemble the power supply. Compare it to Warholic's power supply photos to identify which one you have (the photo of the "EE" power supply is mine, by the way). Note how many of the Warholic- numbered capacitors are bulging/leaking. If your iMac were mine, and I noticed any leaking/bulging caps in the power supply, I would replace them now rather than wait before they failed and caused damage to the logic board. I also would do the same with leaking/bulging caps on the logic board, especially the five directly above the power supply noted by Warholic. Be aware that even caps that look OK could be "bad." However, the one G5 iMac I restored to good health was the only one of the three that had *no* bulging/leaking caps on the logic board. But I did replace them anyway. Cheers!
