Motherboard: Gigabyte P67A-UD3P-B3
RAM: 8GB Patriot DDR3 @ 1600mhz
PSU: Cooler Master G750M
GPU: Gigabyte GTX 770 OC
SSD: Kingston HyperX Fury 120GB
HDD: WD 320GB
Case: Cooler Master Storm Enforcer

Im thinking of getting a bigger HDD because i only have 50gb left on it or getting some good quality fans for the corsair radiator and the rest of the case. Thanks

I wouldn't bother with the Kraken. If you want cool your CPU with aftermarket stuff an waterblock is a better idea, but totally unnecessary.

Your SSD should be full or you're not taking advantage of it. I'd be installing games onto it.
