the heatsinks are nickel-plated copper, applied with arctic silver epoxy. the thermaltake crome orb (also knows as crorb) was seated with AS3 (as AS5 was not yet available). i was able to get 275/530, up from 240/500 stock - which was a very decent overclock on air with no volt mods.
and yes, we are indeed nerds, give or take. but this does make an awesome wall piece, don't you think? i just haven't had a chance to hang it, as most of my free time is spent playing HL2 and UT2K4.
