Built this computer right before Haswell launched.
Asus P8Z77-V Pro
Intel 3570k (4.3GHz OC)
Cooler Master Hyper212 Evo
Gigabyte GTX 760 Windforce Rev. 2 (Clock offset: 110MHz, Memory Offset: 1350MHz)
WD Green 2TB HDD
Corsair AX 750
Cooler Master Elite 431 Plus
And for my monitor I'm rocking an Asus VG248QE. Thinking about buying the G-sync module and installing it myself.
Edit: Forgot to mention it's my first build, and I couldn't be much happier with it.
