Okay, I opened up what you had on your link in the opening post. I did not read all the pages since you're going to order soon.
Here is what I would take out in order of importance.
1) Windows vista. Need I say more?
2) OCZ Freeze - > Use Arctic 5 instead since your HSF is the Xiggy.
3) The Asus 4870. It's Asus, stay away, end of story. Get a better brand with a better vapor chamber cooler on it.
4)G skill ram. It does not OC well, you're buying the e8400 Wolfdale. I know you're going to OC, get better ram like Mushkin or some other brand that OC's well.
4. OCZ Plat.?
