New Build, looking for input

Well, I'm putting my first build in a few years together. I acquired a thermaltake Armor series case (the full tower black one with the side fan) new in the box at a garage sale for $25 so I plan on using that.

This will be primarily a gaming machine, and I just bought a 24" Dell Ultrasharp 2408 monitor, and have a 22" samsung that will be my secondary display.


Here's the parts that I picked out and I would appreciate any ideas where I can shave some money off or if you see any good areas for upgrades that I missed.

PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E168... $150 right now.
CPU: http://www.newegg.com/Product/Product.aspx?Item=N82E168... $320
GPU: whatever 4870 is in stock at the time i make the order $310
Motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E168... $290
RAM: http://www.newegg.com/Product/Product.aspx?Item=N82E168... $92 (does have a $35 rebate though)
Cooler: need input here, I want to do a moderate overclock (like upto 3.2)
hardrive: http://www.newegg.com/Product/Product.aspx?Item=N82E168... 2 of these at $210 a piece


thanks for the help, I already have a retail copy of XP, mouse, keyboard, and gaming headphones.
