Few words.
Case is full-tower with very easy access to the PC internals, plenty of fan mounts, nice big window and it has three 5.25" external bays. It comes either with black finish with red LED front fans (2x 140mm) or with white finish with white LED front fans (2x 140mm). Both variations also come with 1x 140mm rear exhaust fan.
It's one of the best full-tower cases available.

PSU comes directly from the best PSU OEM, Seasonic. 80+ Titanium, fully modular and 10 years of warranty.
PRIME series is the best that Seasonic offers. And at current date, PRIME 650 is the best 650W PSU money can buy.
For your system, 650W is more than enough, even when you go with 2-way SLI on your GTX 1070. Two GTX 1070 in a 2-way SLI peak at max 330W. Add the rest of system at about 200W and total system peak would be 530W.
