blame bigben2k for that link, he posted it up elsewhere
. I have found stuff like that before, unfortunately when i asked for prices etc the minimum order was £100 and it had a lead time of 6weeks. Can't remember precisely what company i contacted atm tho (thought it was in my favourites, it isn't :\). Anyway, that put me off a bit and i didn't bother placing an order at that time.
To further how i was going to go about dealing with the PCB board, i was going to build a completely new enclosure which corresponded to the ATX specs (in dimension at least) out of Perforated Steel sheeting (RS 447-5284), i've already used this stuff to replace the cover on the PSU (would give u a pic but no cam :|). Then i was going to move the PCB about halfway up in the case, put a copper plate on the bottom of it, bring the Mosfet etc wires round from the top to the bottom of the waterblock. This however has left me without a clue on how to deal with the Transformers etc, but it sounds like it could be easy enough to relocate them as well, possible on their sides to contact the waterblock.
Anyway, i'm typing half thought thru thoughts here, sounds just like your idea now that i'm typing it lol
