Alright ladies, it is finished.
I installed Windows 10 64 Bit from my previous post - per JayD, all I had to do was just click that tick mark myself and click "This is my device".
The top has a screen which I took off to show the 2 extra exhaust fans I added:

The case is pretty huge. All the wires are in the other chamber, so it leaves the motherboard and all the parts very clean. I also added an extra 1TB HDD.

I played the following games on the highest graphics settings:
Witcher 3,
Dirt Rally,
Skyrim,
CS GO
And maxed out fps in each, and the 1070 didn't seem to have any trouble - barely hit 65 C
