no power, bulging caps x6

文本:

hi gurus,
 
have just opened up my g5 1058
 
The short version of the story is that i've bought this as a dabble into the world of mac's. The story was won't power on...so I opened it up and found 6 definitely bulging caps. I've read this is common to these models and would like to have a go at replacing them, I've also read that you guys think this is a difficult repair job! So.. ? Have you any masterful hints and tips to remove them as the common thread is that it's difficult with these layered boards. Any help greatly appreciated.
 
also read a few articles about this on badcaps.net and one linked from previous questions which suggest "rippling"..now I'm not an engineer, I'm an ordinary citizen and I was lost after the first hyperbolic graph and accompanying abbreviations. My general understanding was that all? the caps will need replacing, and so will the PSU as this is the source of the "rippling". Am I on the right track here or am I confused?

hi gurus,
 
have just opened up my g5 1058 have no emc on back of mac to tell you which one it is, and as it won't power on i can't tell you anything else..but if you can tell me any other way to identify which one it is that'd be a great help.

So.. do I need the exact model number in order to find the right replacement caps or are they common to all imac g5's? Have you any masterful hints and tips to remove them as the common thread is that it's difficult with these layered boards. Any help greatly appreciated.
