I will have an i7-3770k, Gigabyte GA-Z77x-UD4H motherboard, G.Skill Ripjaws X series 16gb 1600 for the RAM, and a Sapphire HD7970, all in a Fractal Design Define R4 case. Right now I'm thinking the Noctua NH-D14, but I was wondering if anybody had better ideas. Please leave room for future upgrades in graphics cards and RAM. Also, watercooling options are okay, provided that they are within $10 or so of the Noctua. Thanks!!
