GPU fine but pretty old, better get an ATI 6870 1GB (same price better performs) later on do CrossFireX, it's scaling would be better than the GTX 460 in multiple GPU setup.
RAMs fine, make sure you get 1600MHz ; not much price deference and that speed is a sweet spot for sandy bridge CPUs.
PSU I personally would get Corsair power supplies (TX750 in particular) solid as rock, Antec doesn't supply power cord, how cheezy.
Case fine, I personally have HAF 912 Advanced so far.
Since standard edition lacks in black interior I'd advice you to see other deals and get the one which has black interior (that is CM 690 II Plus).
Get this CPU cooler:http://www.newegg.com/Product/Product.aspx?Item=N82E16835103065
It's good for mid OC'ing (ie 4.2-4.4GHz).
All the best.
