The max component repair I have done is DC Jacks on a laptop. I have trumped my previous experience and am proud to show off what my skills have yielded. It took 3 hours (1 hour just to cut the silicon crap out of the PSU), but after following these instructions and buying the parts off that website, I have resurrected an iMac G5 1.8Ghz w/ 1.25GB RAM

The symptoms are the typical. Sporadic shutdowns, sometimes not turning on, then not turning on at all. All-in-all, 7 of the 9 capacitors that I had to replace had either vented, or had bulged and were bad. I replaced the non-bulging as well, including getting to a really hard capacitor to replace (see the image where it points under the heatsink).

3 hours later, I am up and posting on said iMac (see picture) and it runs great. it's been fine, steady and no issues that I can see. The new caps should also be more sturdy.

This is the worst component replacment I have done to date, with the previous worst was a 3 capacitor replacement on a motherboard.
