Mobo: ASRock Z77 Extreme 4
GPU: Gigabyte GTX670
CPU aftermarket cooler: Hyper 212 EVO
RAM: G.Skill RipjawsX DDR3 1600Mhz 8GB (2x4)
PSU: Corsair CX600W
Case: HAF 932
Anything you'd change? Particularly interested if the PSU I chose is going to cut it.
Do you plan on possibly SLI in the future? If so, you need to up your PSU to the 750 watt version. If not, then you will be fine.
I would replace the Gigabyte 670 with the MSI 670 Power Edition.
Can't go wrong with the 3570k, best you can buy right now.
Finally, I would replace the RAM with low-profile stuff like this.http://www.newegg.com/Product/Product.aspx?Item=N82E16820145324
Hope this helps!
