A bit pricey is my only gripe.
- If this is a gaming build, you don't need an i7. Go with i5-3570K.
- Drop the 256GB SSD with a 128GB SSD + HDD. But the choice is yours.
- I'd also drop the Asus Z77 Sabertooth with an Asus P8Z77-V LK or ASRock Z77 Extreme 4.
- Patriot Gamer 2 (2x4GB) RAM
- As for the closed loop water cooling, if you're going to water cool, construct your own. Otherwise, a Noctua NH-D14 is just as good in performance.
