and BTW the Monitor is 1680 x 1050 and yes, there will be (at least attempted) Overclocking

Oh and this HSF
COOLER MASTER Hyper 212 Plus Intel Core i5 & Intel Core i7 compatible RR-B10-212P-GP 120mm "heatpipe direct contact" Long life sleeve

You could likely skip the TIM, as well.

If you're only running a single video card, I'd suggest this PSU.

Most onboard sound is good quality now days, so I would drop the soundcard.

This would be one of my favorite cases around the same price

If you're running windows 7, I'd suggest looking for a 5850. If not, I'd suggest the ATI 4870 or 4890. They're much better price/performance.
4890 - http://www.newegg.com/Product/Prod [...] -_-Product
4870 - http://www.newegg.com/Product/Prod [...] 6814131148

With the $$ saved, you could upgrade your monitor to something like this
Acer 22"
