Ok, ThePCPicker24, I looked at your build and here are some notes. First, you choose K version of CPU. This is one you can overclock if you want, but then you need a motherboard with a Z in name, like Z170 instead of B150 (B are the most cheap). If you dont want overclock, then just get cheaper version and you don't need a special cpu cooler in that case. The standard cooler with your cpu is enough. Also case fans are not necessary, as your case does have some. All these extra stuff is just needed, if you really want replace loud parts or want overclock.
Second, I can recommend you to buy a SSD drive, which will dramatically improve installing and loading time of Windows, Apps and Games. Its one of the best things you can buy for a pc. 250 GB is not big, but plenty for Windows, Apps and some big games.
The GTX 1070 is a very powerful card and should be enough for you request. I own a less powerful card the GTX 970 and it almost meets your requirements. Btw, do you play at Full HD resolution? 1920*1080. I would say, even a GTX 1060 should be enough for you, which is a little more powerful than mine GTX 970 previous generation. I replaced it to 1060 in this case.
Next thing, the psu is not bad but not first class. There are some other better one (also from EVGA made by other psu makers). If you don't mind, I recommend you a different one here.
And then the CPU. If you have the budget, then get the i7 processors. Some games and probably later newer games will thank you for that with fps. I bet, you will not change cpu once you buy it. So think about it. Some games really works better with better processor and if you want a gaming machine primarily for gaming, then this is a good step. From my prevous talk about K version of cpu, even if you dont overclock them, they have a higher base clock. So you can take this in consideration.
Ok enough talk. Here is a variation of your build:
