I definitely agree with cutting down on the CPU. I also agree with the choice of the aforementioned motherboard.
Also the HAF X is a monster, you don't need it unless you're running an XL-ATX board with a custom loop. You can get an NZXT Phantom or NZXT Switch 810 - and save like $100.
Take that $200 and invest in a good SSD like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16820147135
