a few weeks ago i talked scousethief through the procedure, he had concerns about doing it, in fact he posted a thankyou on here to mulja and myself.
the caps, electrolytics, are tied up with the 5v line, two other caps are in the primary of the main psu, there is also a 3 pin ic fitted, we use them a lot and obtain them locally, usually chs but try giving the smaller traders a chance, i recommend ohm supplies, and theyrre cheap

just tell them the number on the psu and they will sort you
