Dunno if this helps you any, but out of interest I decided to take a look at the logic board from one of these eMacs that ive already pulled apart, and found this board which attaches via a socket...



With this buttload of bad caps...



At least 7 of them have popped up ends and leakage/corrosion... a 2200u 16V, a couple of 3300u 10Vs, a 1000u 16V, and 3 1200u 10Vs. thats at a cursory glance... No other visibly damaged components but ya never know.
