145 no power, bulging caps x6
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?
Это хороший вопрос?

interestingly the only caps that are bulging are nichicom 1800uf 6.3v..am I right in thinking as these 6 are different to the rubycon on the rest of the rows that these have been replaced once already?
