great build but i would suggest the following changes-
as some one else said,cosmos ii is definitely not the best case and for $350,it's way overpriced.800D is a good alternative.
for me,there's no difference between home premium and pro.why spend more?home premium is fine.
from this saving,you can get a really nice 240gb ssd-http://www.newegg.com/Product/Product.aspx?Item=N82E16820226226
and i don't think LED TVs provide you best gaming experience.
