350 dollar PC

I'm looking to build a PC from 350-500 I already have a case, psu, optical drive, and an os. I would really appreciate it if you left me some good suggestions.

Let me just point you at tonight's Tek Syndicate video: https://teksyndicate.com/videos/build-350-pc-plus-upgrade-options-cheaper-consoles

I saw the video I was just wondering if I could get more powerful hardware since I already have some of the stuff I need.

It's 750 watts so it does.
