1. Don't need a i7 975.
2. Don't need a Z-Drive unless you have a special need for fast access to files (massive file server,etc).
3. Over kill on the motherboard.
4. No need for a 1.6kW PSU.
5. WTF? Why are you running Dual Channel on a Tri Channel board? (esp. given the fact you seem to be able to afford a EE CPU).
6. Overall, a good wast of money.
