OMFG those are scary, and look tight!
make wure when you get that beast, blow off that dust!!!
and if you have a case that has a power supply thats vertical, that would maybe work better than a horizontal ps.
The critical capacitors are totally hidden by the overhang of the HSFs, so you will have to remove them to get a decent look at the Caps.
Well, maybe the one at the edge can be checked - but kind of fuzzy in the PIC.
