Well, I got it built last night and it's great! Fast and quiet; exactly what I wanted.
I'll be reinstalling Windows 10, but I'm very impressed with how it handles itself when transferred directly into a new system. A few minutes of setting up devices and I was onto the desktop and firing up games and benchmarks.
I managed an easy 3.8 GHz overclock, but couldn't get the memory to run anything but 2133 MHz (it's rated at 3000 MHz) with the presets. I'll have to spend some time reading up and going through the advanced settings tonight.
