A very good build.
One can nitpick preferences for parts, but you really need change nothing.
My nitpick:
I will never again build without a ssd for the "C" drive. It makes everything you do much quicker.
120gb is minimum, it will hold the os and a handful of games. If you can go 240gb, you may never need a hard drive.
I would defer on the hard drive unless you need to store large files such as video's.
It is easy to add a hard drive later.
Samsung EVO is a good choice.
Intel 730 is OK too.
