I like to stay with highly recommended power supplies corsair, seasonic, pc power and cooling to name a few. The one item you never want to go bad is your power supply just a utter mess. I've heard good and bad things about OCZ memory kingston is good for sure also patriot, and corsair are good options. As far as cooling I really like Zalman if you are looking into aftermarket cooling very affordable and easy to install compared to most after markets. EVGA great costumer support can not go wrong with them. All and all your build looks good just make sure you don't go cheap on the items you need to have with really good quality PSU, CPU, etc., and best of luck man.
