What do y'all think of this build?

Solution
If you're going with a mid atx case, don't get a mini itx board. Get a regular atx board. This way your internal components will be spaced out for better thermals.

+1 on that, that motherboard is gonna look like a postage stamp in that case. Plus it will never overclock that well.

That cooler you selected isn't that good the Cryorig is cheaper and way better. The PSU was way overkill, unless you plan to SLI 550 is more than enough.
 
Agreed, zerro reason to get itx board (which usually costs more vs atx conterpart) to go into case designed for full atx boards.
If you are buying it jsut for wifi dont.
I would advise tryinging powelrine adapter over wifi (assuming you cant just hard wire PC to router).

Why that cooler, it is massive, a complete PITA to install from reviews, and wont make much of a difference vs 212 evo or cyrog c7 at half the cost?

Other then that it looks good. 750w is right on the money for a 1080 while running a good overclock, the 650 would work but not leave much head room

I don't agree 750 is extremely excessive. 550 is fine even overclocking both CPU and GPU.
