Well, you know windows 7 aint out yet...so ull prolly wanna include windows vista in the price list

I wouldnt recommend a 22" monitor at 1680x1050, 1920x1080 or 1920x1200 would look better for about the same price. Personally i would rig similar to yours, but with a few changes:
Rosewill Case: $49.99

All that comes to.... $980.91 before rebates, not including monitor. After rebates it comes to $895.91, And then i would have to recommend this monitor:
Asus 21.5" 1920x1080 monitor $179.99

With the monitor it would be $1160.90 before rebates, and $1075.90 after rebates. Just a few notes on this over scouts list is this has a motherboard with sli capability, so down the road you could add another Gtx 260 to get nearly double the graphics power, Faster memory, a better cpu cooler(The zalman 9700 is more geared towards dual cores, S1283 is alot better on a quad), better gpu, and a higher output power supply. If you are looking for a monitor, keyboard and mouse included in your rig then i would go for scout's list, but this list here would give you a little bit better performance, although i would recommend the 1920x1080 monitor on either build

Plus you need to have an operating system such as windows vista x64, as windows 7 can only be acquired.... in ways that cant be talked about here
