That's a pretty good selection for the most part - love the Corsair Carbide. 16GB is unnecessary for a gaming rig however. The extra fan is also unnecessary - the Carbide is extremely well ventilated and includes plenty of fans to start with - but you should also get a Hyper 212 Evo if you're going 2500K.
As far as the GPU goes - the 6950 is decent but it's based on aging architecture. You should check out the new 7850 as it's been completely redesigned from the ground up and getting rave reviews: http://www.newegg.com/Product/Product.aspx?Item=N82E16814102984
