My Proposed System

[Veanie]

Asus P5WDG2-WS Professional Intel 975X
Intel Core 2 DUO Extreme Edition X6800
Corsair 2GB DDR2 XMS2-6400C3 TwinX

ATI Radeon X1950 XT-X ***Crossfire/Master Edition***
HIS ATI Radeon X1950 XT-X ICEQ 3

Antec P180 Advanced Super Midi Tower Case
Antec TruePower Trio 650W PSU

Adaptec AAR-1420SA
4 x Seagate Barracuda 7200.10 250GB *ammeded*

Any problems or silly mistakes ?

Is a 650w PSU enough grunt for this system ?

Does anyone have an Antec P180 case ? Would a 220mm long PSU fit (thinking of a Galaxy)

Good and accepted point regarding the hard drives, build ammended.

Yes PCI-X is required for the RAID controller.

The Seasonic PSU is nearly and inch longer than the Antec and the case is seemingly very tight on space.

Would welcome anyone with the case to let me know how much room there is to play with in the PSU compartment.
