Im making my own computer?

Don't get that PSU; it's old. At least get the TX750 V2. You also don't want an H61 board. For a 2600K you'll want a P67 board. I'd go for the ASRock P67 Extreme4. It's affordable and has an awesome feature set. As for the 2600K, consider the 2500K. You'll notice no difference in games, only in heavily threading applications in which the 2600K's hyperthreading is used. You also need RAM. I'd get 4GB of 1333Mhz CAS8 RAM for $50.
