First time PC for gaming building

[Kvarcas]

Hello, for a first time building PC and i would like to ask someone for some advice.

There is all parts i picked. I need someone to check and say if there is any changes needed. Example i took Asus Geforce GTX 1070 8gb but maybe MSI would be better or any other modification of those asus cards since i can see there is many modifications and its confusing.... Also about cooling i am not sure if i really need that cpu cooler, maybe i can take cheaper one and it will be good enough... Please advice and guidance...
PC will be used for gaming, cinema and internet.

it's a good build however the PSU is poor. you'll need to swap it for a better unit
the WD Black is a nice drive, I got it myself along with a barracuda and I gotta say, I don't feel the difference in speed but I definitely hear it. out of a dampened case. so I advise against it generally.
when it comes to the 1070 there's little point in buying an expensive 1070 as with boost 3.0 they all perform the same. for example, my Gainward Phoenix GS, boost clock of 1835MHz boosts without any modification beyond 1970MHz. so there's no need to spend extra escept for aesthetics (and maybe EVGAs ridiculously good customer support in north america)
if you further wanna save a few bucks, I'd pick a slightly cheaper but quality motherboard and reflect the need for the 850 Pro SSD. The 850 Evo might be just fine for you and reduce cost for another 30$

this is what I'd go for:
