1) Drop the second Raptor. Read the article here about RAID 0. It's a waste of money (slower or equivalent performance). Also, $240 each!? My 74GB Raptor was $179 minus a $25 rebate = $154.
2) Buy a Logitech MX Duo. Why do you need Bluetooth? The standard MX Duo is over $100 cheaper at Newegg, and it's the exact same keyboard/mouse. I have two; they're great. Heck, you could go with a $10 wired keyboard and optical mouse that would work just as well.
3) Why spend $150 on an optical drive when you can get a NEC 3520A for ~$65 on Newegg that'll do the same thing--you can't even buy media for either drive anyway.
4) $390 for an unreleased OS, that'll undoubtedly be full of bugs and incompatibilites? Go for the 32 bit version of XP Pro. It's $150, and it's stable and will be faster in games and benchmarks for now anyway.
5) "Trend Micro PC-cillin Internet Security $49.95".....uhhh....why? If you're going all out on this serious water cooling setup, then surely you can manage your own dang computer without the help of extra software. Use Adaware and Spybot every few months, and you'll be fine. TrendMicro offers free online virus scanning as well. In the 5 years I've been running without "protection", I've never had a problem. Windows XP's (lame) firewall and my cheap Netgear routers have done a fine job.
6) "Logitech X-530 $79.95 "....you might as well drop the speakers entirely and keep whatever you're using now.
Total: Over $880.98 of savings, and performance will be better. You should shop around. As I've already pointed out on several items, your prices are extremely high. Try Newegg, or Pricewatch in combination with Ressellerratings.com (I don't buy from stores with ratings lower than 7.5).
You'll surely save much more $$$ after finding better prices. Also, you may want to consider a different SLI motherboard and PSU if you plan on meeting your price target. Newegg has an SLI board for close to $220, and an Antec 550W PSU for around $150. That'd be another $240 you could save.
