I was wondering if this looks like a solid $600 build i will be doing shortly(Next 3 weeks) i just got paid and its time to order my parts!

the corsair CX600 (600W) psu is $10 cheaper than what you selected for your psu, http://pcpartpicker.com/part/seagate-internal-hard-drive-st1500dm003 3 times the storage for $20 more
for the memory, i would suggest getting a 2X4gb kit over the 1x8GB kit, so that the memory will run in dual channel instead of single channel
