Velox vs Apollo Build

Budget:
$3,000 - $3,500

Expectations:
Want this as primary gaming computer for 4-5 years. Plan on buying an Acer Predator 1440P monitor.

Concerned about cooling, noise reduction is nice but not necessary. Wasn't sure about what case was better Velox or Apollo

Usage:
Gaming (Fallout, Call of Duty, Company Of Heroes 2, Endless Legend, Stellaris, Crusader Kings II) and general computing (web, photo storage, MS Office)

Special Needs:
Will be using secondary drive for data storage. Plan on backing up to external HD periodically and storing off site. Want fairly fast backup so thinking USB 3.0.

What is the difference between the ASUS Z170-PRO GAMING and the ASUS MAXIMUS VIII HERO motherboards?

Thought Velox would help cool better because I wasn't planning on water cooling the graphics card. But am overclocking to Stage 1 on the CPU and chose HydroLux Lite since Noctua isn't an option. Should I add additional fans or is this config good enough?
