hmm, what about just a higher quality PSU to start with?
i.e. pcpower and cooling silencer 400
here
It's allready designed to run cooler, ahh but no fans to suck any heat it would still get a little toasty. I see the problem again. but I wonder how hot the components would get?
Maybe ramsinks attached to the Caps
though you would still have the problem of getting the heat out of the PSU in the first place.
Shuttle's heat pipe? mmmm, probably get to warm just for it to even work properly.
