Yeah man, great choices. Remember to shop around for that window 7 OEM. Often times you can get them cheaper than newegg.
Also, I just want to point out that your case has blue LEDS and the strip is red LEDS.
Also, if you're in the USA...
You should make the case take a 360 radiator, but instead of being a straight line have it be an L shape, and design a custom hydro series for it, or just a radiator. 8o
I'd say for for one of them lil' baby cases with the lil' baby PSU built in to the lil' baby case. I'd stay on course for the quad core, if they managed to keep a desktop for ten years some extra future-proofness is probably a good bet....
