Opinions on this build?

I don't see the need for such an expensive mobo. So many good choices for under $300 that will perform the same. Then you could invest in custom cooling. Or how about a NZXT X62 cooler? Otherwise, looks solid. The PSU is still more than good, and SSD is fine. Although I personally need at least a 500gb SSD for OS, programs, games.
 


Only change I'd make is the RAM. G.SKill makes the best looking RGB customizable RAM. Trust me...it looks worlds better than what Corsair offers. I have it and love them. Adds an extra pop to the build.

Memory: G.Skill - Trident Z RGB 16GB (2 x 8GB) DDR4-3200 Memory ($224.99 @ Memory Express)

Only other suggestion, I prefer Asus:

Video Card: Asus - GeForce GTX 1080 Ti 11GB STRIX GAMING Video Card ($1009.99 @ Newegg Canada)
