Hmm. I'd say don't try to spend all of the money because it'll just end up going to waste: Vista Ultimate 4gb's Corsair Dominator (the fastest you can get) Asus Striker 2 Raptor-x 150's in raid 0 2 750gb HDD's in Raid 1 2 8800GTX's with the blocks on them Dangerden Cooling with a triple GTX radiator Lian-li Server case Quad Core Core 2 X-fi Platinum Pro 30" LCD from Dell or apple Kick ass Hi_fi speaker system Put a chunk into a secondary HI-Def screen for video's and stuff Then save the rest in an account just for PC Hardware and re-upgrade when the new quad cores come out and DDR3/New videocards bla bla bla I know you can spend more but you won't see any improvements so it'd be like throwing money away.
xserve video editing cluster :] that should keep him busy for a while, great fun too but other than that i'd go clovertown + 4gig ram + 2x 8800gtx and some gaming laptop for some fun on the go
servers are pretty much useless for gaming, the ram uses error checking which slows it down. just get c2d extreme quad core, asus striker extreme, 2 raptors, 2 of those 750GB hard drives, 2 8800GTX, and as much ddr2 1066 that you can fit into that board. if you dont wanna run that in raid just run them for file storage, and use raptors as main hard drives. get a case to fit and good aftermarket coolers unless he knows how to keep watercooling up and running. simple but effective.
I'd go with what others have said, except no hardisks, instead a 4GB/s Fibre Channel storage adapter (8GB or 10GB in a couple of years), wired up to a RAID array full of 15k RPM disks (either SAS or FC), which should give enough speed to do pretty much anything (2x that of an x-serve), with a direct point to point fibre link, it'd also have a good low latency with the stupidly high bandwidth. Then I'd buy a cheep box to act as a Linux server: http://www.sun.com/servers/highend/sunfire_e25k/specs.xml
i am kinda curious on why a very rich person would require 1TB+ in storage considering he dosen't have to download all his films and music! lol if he wants to play games then i would get a ''Sony KDS-60A2000'' thats a 60'' screen that is also HD 1080i Then the usual SLi 8800GTX's water cooled, then i would go for a Intel Quad core under phase cooling clocked to the nuts. oh and a perfect audio set up!! no X-fi at all, just go pro with an external amp.
