Complete build for around 2k US$

[Spancer]

Hey guys I need some suggestions for a new build.

 

I need a new PC since I'm not home weekdays and I want to keep my old build at home to play on the weekends.
I want a PC that is capable of running games at 1440p for the forseeable future and also watching movies/youtube. The budget is around 2k$ for the new parts.
I have a second monitor and a WD Black 2TB lying around, so that's the reason I didn't add more disk space. I can also get a Win10 license cheap from my workplace.
Is there anything outdated or something that I should change?

Everything seems fine, that monitor seems a little expensive though.

Seems like a really well put build to me. I would not change anything. 

Well maybe the RAM so it doesn't look so white/grey with a black and red motherboard

NVM, case has no side panel

Seems like a good setup/pc build.

Looks find to me. I think that this is a fantastic build.

Alright.

What do you think about the headset? Are there better options in the pricerange? I prefer open ones if possible.

Also, don't really care about the inside look since there is no window in the case.
