build looks good, one thing I would note as for the Samsung 840 evo, you could probably find a 256gb for like $20 more than the 128gb. And for the gtx 770, you more than likely don't need the 4gb cad, a 2gb would be more than fine. Tests have been run and show there is little difference between performance on 2gb vs 4gb, and the 2gb is low $300's vs the 4gb being high $300's. But otherwise good.
