I'm looking to spend about $1500-$2300 on a linux system. I want all the bells and whistles (berly/compiz/whatever), good sound, etc. I would like to know what you all think is a good list of parts for a system so that I can use every piece of it to its fullest extent. The specs I was hoping for were:

-4gigs ram
-64bit dual or quad core (amd/intel doesn't matter)
-1Tb storage
-raid 1+0 perhaps those raptor drives
-SLI (perhaps 4 screens or more)
-and anything else that'd make a geek drool

The reason that I'm asking for this is because my 2 current computers don't work well with linux (one is a freakish blend of parts all the way from 1992 to 2007, and the other is a laptop that has some funky sound chipset I've never seen before and can't seem to get to work on some distros.) I could just go to newegg myself and get a bunch of parts, but then I risk getting some incompatible parts, so....any of you with the uber system, post it up here please.

Thanks!
