Im in aus so i'm not 100% on the pricing.
I went for the 5870 XFX XXX edition cos the GTX 480 is too expensive.
Cooling is not included (apart from fans).
Case accesories are not included.
With that hardware you would need watercooling and a would have phase change for the cpu.
I wouldn't spend all that money on a pc!
IF you want good cooling and other things i'd get the i7 930 which is WAY cheaper and easy to overclock on phase change and watercooling. u could also start with say 2 cards instead of 4.
To build the best you would need $10,000.
That would include watercooling, phase change, multiple SSD in raid. heaps of accesories, 4 gtx 480 FTW edition with inbuilt waterblocks etc.
If you want to ask me anything please do however i'm quite worried that your blowing that much on a pc when you don't no what parts you want (i.e. dont no that much about computers) A tiger pc would need modding aswell and serious overclocking!!!
And some of the things i list were personal preference (ie the case)
