For your video cards, maybe you could opt for BFG instead of ASUS. BFG offers lifetime warranty on them too. Not saying ASUS is bad, but I like BFG's warranty. Also considering they are on special this week at NCIX, now would be a great chance to buy them.
BFG GeForce GTX 295 576MHZ 1792MB 1.998GHZ GDDR3 PCI-E Dual DVI-I HDMI HDCP Video Card
So, I'm guessing you need a lot of crunching power to do your rendering and such right. Your RAID SSDs would be make sense and I'm guess all your applications will be installed on that RAID correct?
Also, I noticed... you don't seem to have a Power Supply (unless my eyes are starting to fail me

). But with that much power being drawn... I would go for a 1000w minimum. Then I would suggest this one:
Corsair HX1000W CMPSU-1000HX 1000W ATX 20/24PIN ATX 80A 12V Afc Modular Power Supply W/ 140MM Fan
You'll have plenty of power with that one, and also plenty of power sources (SATAs, 8 Pins and so on)
Nice Rig BTW, I would love to have that kind of budget for a computer
