So here is the Semi-Final build with a few pictures.

Specs
Motherboard : Asus z7s WS (Bios Rev:401)
CPU: Intel Xeon x5450 3.0ghz Quad core X2
Memory: Dell DDR2 FBDIMM 667 8gb ram( 2x 4gb sticks)
Video card: ATI 1900gt (next on list to change)
Cooling: Swifttech Dual 120mm rad.
Thermaltake Single 120mm Rad.
Koolance 301 CPU water blocks
Thermaltake Ram Coolers (Passive)
Case: Thermaltake Armour Series case

once i get it burned in, and running stable, the overclocking will begin. The thermaltake Case , i must say is the best case i have used in a long time. It droped my 45C Motherboard temp to 35C and it never budges from that.
CPU 1 stays from 38c to 45C under load, but cpu2 has jumped as high as 65c and i had to kill the stress test to save it. The second rad. for that cpu doesnt have a fan yet .. once i get a fan on it, ill see if the temps stablize..

As for the OS, i am running a Dual boot Config. 2Sata 250gb HDD for Windows Vista x64 and 2 Sata 250GB HDD for Leopard OSX with a 1TB storage drive to swap between the 2.

Here are some quick pictures of the almost completed rig, i took these last night at 12am, so ill get better ones soon.
