mfenn's original build is better than that for nearly $200 less.....
In detail:
Coolermaster Hyper 212+ is a cheaper and better cooler.
As usual, you don't need the 2500K if you don't have a board that can OC it - so either swap the CPU to 2500/2400, or swap the board to Z68. Mfenn's asrock atx z68 board is the same price as that intel microatx h67. And no it's not worse quality
G.Skill 8GB DDR1333 can be had for $50, you don't need to pay $70 for memory.
Not sure about Corsair Force 90gb, the usual recommendation for an SSD is the Micron-controller based Crucial M4. But it's not available in 90gb, only 64/128. I would get the M4 64gb for OS, and install games on the HDD.
The 650W power supply is still bigger than you need. And why do you want it to be 80+ Gold? That's insanely bad value for money. It's the absolute highest quality product in its class that you can buy, and the same cannot be said for any of the other components. You could get Antec HGC-620 from newegg $50 after rebate and be perfectly happy with it.
