Gaming PC

I really need to get into PC gaming, I was thinking about buying all the parts myself for a gaming rig and pulling a favor from my computer friend to assemble it all.
I need something to run the most modern games, on high detail at 60 fps. And hopefully around 1500-2000$.
I've never built a computer before so I'm kind of clueless on what to get. any advice will be appreciated.

OP here, I decided on these. Any blatant problems/ stupid choices?
