Hey! I just built a very similar PC like you, and I'm using the Corsair H100i v2 L-cooler. I think it's a little bit loud with the dual 120mm fans that come with the AIO. Other than that, I think this is a solid build. Also, since your build is about 2.5K dollars, you might want to go with the 1080 or if you don't build it right now, wait for the 1080Ti (It might be really long or even never)
