With this case, you have a small problem. Your GPU is 298mm long while your case supports up to 294mm long GPU. If you want to use your Asus GPU, you need to take out the HDD tray next to the expansion slot to get enough clearance for your GPU.
As far as the rest of your build goes, your PSU is way too powerful for your PC. You'll do fine with 500W range PSU. And since you picked Z170 chipset MoBo, you can use K-series CPU (that you can overclock) and also much faster RAM than 2400 Mhz.
Also, refined your build.

Changes made
CPU: i7-6700 -> i7-6700K
CPU cooler: Intel's stock cooler -> Be Quiet! Dark Rock Pro 3
MoBo: Asus Z170 Pro Gaming -> MSI Z170A Gaming M5
RAM: Kingston 2x 16GB 2400 Mhz -> Corsair 2x 8GB 3000 Mhz
SSD: Kingston SSDNow UV400 (240GB) -> Samsung 850 Evo (250GB)
HDD: Seagate (2TB) -> Hitachi (2TB)
GPU: Asus ROG Strix GTX 1060 OC edition 6GB -> MSI GTX 1060 Gaming X 6G
PSU: Thermaltake Toughpower 750W Gold (Modular) -> Seasonic G-550
Reasons why
CPU: With Z-series MoBo, K-series CPU would be nice match since you can overclock the CPU if needed.
CPU cooler: K-series CPU doesn't come with Intel's stock CPU cooler. So, added one of the best big air cooler for CPU cooling that has nice black theme.

MoBo: Since you want to have black & red theme, i switched out your MoBo to better match your build theme.
MoBo specs:

(I have the very same MoBo in use in my Skylake build, full specs in my sig.)
RAM: Since Z-series MoBos support RAM XMP profiles, i added 3000 Mhz RAM to your build. MoBo has 4 RAM slots and when needed, you can easily upgrade your RAM from 16GB to 32GB with another set of 2x 8GB 3000 Mhz RAM.
Note: install RAM before installing CPU cooler. It's easier this way.
SSD: Replaced it with better drive while gaining 10GB of storage space.

HDD: Replaced it with more reliable drive. (Note: HGST is new name for Hitachi.)

GPU: Replaced the GPU to be better match to the MoBo's black & red theme.
specs:
https://www.msi.com/Graphics-card/GeForce-GTX-1060-GAMING-X-6G.html#hero-specification
MSI GPU is also shorter (277mm) than Asus GPU (298mm) and you don't have to remove HDD tray to fit the GPU inside your PC.
PSU: As said above, 750W PSU is way too much for your system. So, replaced it with good quality Seasonic unit that too is 80+ Gold certified and semi-modular, just like the Thermaltake PSU.
All in all, the refined build costs $90 less than your initial build.
