ok well, i suggest
the fx60 phase change cooling obviously
2-4 gigs of ram(because 2 gigs will have better timings, but 4 gigs makes for more multi tasking) water cooled and ocd
crossfired x1900xts (because the crossfire card runs at xt speeds) water cooled of course and ocd
a good crossfire board, im not so savvy with the crossfire so i dont know which would be good
the raptors with the clear top duh
a nice case ( cases are all about your personal taste so im not gonna suggest one)
i think you would want a killer psu, and i believe sli certified ones work for crossfire. maybe the 850 watt one? forget what its called.
some nice optical drives
as for the sound card, get the one with its own proc because it takes the load off the reg proc.
hmmm i dont know what else.... you dont need any fans because you dont need airflow as everything is water or phase change cooled.
i guess thats it. not much else cept accessories. as for os obviously xp pro. spend any xtra money on games so you can actually use the beast. i suggest guild wars, cs:s, oblivion, fear, and there are loads others depending on what your into. personally, i think the super nintendo is better than any computer but w/e. still, it would make my eyes bleed to see what this thing can do. so get it.
