I do see a possible conflict between the fan and the memory chips. I went with the liquid cooler to avoid the fan fins hitting the memory chips fins. Do a google search for Noctua NH-D14 images and you can see how the fans fit in with the memory chips. Same with the Video card, is it going to fit in your case?
My last build all came from Amazon, the previous build came from NewEgg.
I went with Windows 8, in spite of dogging it here and in another forum. Most of the builds I've seen here are on Windows 7. I did have to upgrade a couple of non -DAW programs for Windows 8.
I recommend looking up the items you are installing for your build on YouTube. It sure made my build go easier.
Looks nice, BTW.
