I downloaded the manual and the QVL here is my parts list so far....
ASUS Z170I PRO GAMING (only 2 dimm slots up to 32GB total)
Intel Core I7-6700K
Corsair Hydro Series H60
Samsung 850 PRO 256GB
WD Black 1TB Performance
EVGA SuperNOVA 550 GS 80+ GOLD
EVGA GeForce GT 710 2GB
Corsair Obsidian 250D
Need to get RAM and Windows 10 pro. Was going to get at least 2666MHz but maybe 3200MHz. Not sure if I'm going to overclock yet I will see if I'll need too. So I wanted to get DDR4 that was fast enough if I want to overclock in the future.
Here is the QVL list...
