Guys, some important info in case anyone wants to build another monster rig using the Z7S:

Do NOT use the Intel 9 series chipset drivers if you're running a Raid 0 with 2 Velociraptors and Vista 64.
Took me all of one day to figure out what went wrong, I experienced severe stuttering during 3D benches (Far Cry 2, Crysis etc) and eventually, freeze/BSOD. Also the Intel Storage Manager kept claiming one of the HDDs was faulty. So after scanning both drives repeatedly for errors and finding none, I just reinstalled Vista and this time, used the drivers from the Asus CD (which contains version 8,6 of the Intel driver) and voila, it works just fine now.

Rig specs: Dual X5450, Dual HD4870X2 CF, 4x2GB Buffalo FBdimms, 2x 300GB VR in Raid 0, 1TB WD RE3, Dual PSU, CPUs/GFX/HDDs watercooled, Dual pumps, 3 Dual rads

Maybe some pics tomorrow
