looks like a solid build
i can't say i know much about the new P67 mobo's
a solid PSU, assuming its enough power for you, one needs to think about future upgrades (newegg has a PSU calculator that tells you the recommended wattage)
great SandyBridge CPU, should provide some good OCing headroom (i assume thats why you got the K series and an aftermarket fan)
Great HDD, i have one myself. Just make sure TRIM is enabled and AHCI in the BIOS.
The rest look good too... although for monitors i always recommend a 1920x1200 monitor, a little bit wider than standard 1080p
