That build would work, but with three suggestions: upgrade to i5-3570k, as it is much better than the 2500k (unless you want to overclock), but if you are, then get a cm hyper 212 evo, they work great for O/C. Also, you should try this HDD http://www.newegg.com/Product/Product.aspx?Item=N82E16822236338,
it's a caviar blue, but it still works great and you get 250GB more space and SATA 6GB/S, which is almost twice as fast for the same amt. of money (according to Newegg). Finally, you should get a lower wattage power supply (unless you are O/C). I would recommend Corsair's builder series http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027.
You can still upgrade and/or get a decent overclock out of it.
