Looks good from here. All you need is a power supply, cooling, and storage. And a case of course, which I will not recommend, as it is the user's choice.
As for cooling, I would recommend the Noctua NH-D14.
If you are not running more than one card, you can stick to a smaller power supply. Something like the Antec NEO ECO 520W or the XFX 550W should do.
Thanks a lot for the suggestion. I'll consider those in the build. I assume Noctua NH-D14 will give enough space for the head spreader of the RAM right?
