This is going to replace my last Akasa Eclipse, so I'm going to use the q9550 and Rampage Extreme I have left over after upgrading my main rig to i7.
Specs
Intel Q9550
Asus Rampage Extreme
8GB Corsair Vengence
Asus Geforce GTX 570 (to buy)
Asus Xonar DX PCI-E (to buy)
3x 640GB WD SATA II RAID 0
Corsair AX750
Corsair A50
Coolermaster CM-690 II
One of the CM-690's I have I plan to water cool, but that will have to wait until I have finished the upgrades.
I should have the parts I need to start this next week.
