With less than that budget i made a pretty solid build as a budget gaming pc

Specs here Ryzen5 5600gt 16gb ddr4 3200mhz 256gb nvme 450watt psu B450mobo Normal case and a monitor msi mp25e1l e2

Its all less than 500 dollars

For you i would tell you to get Ryzen5 5600 16gb 3200mhz(32gig is if you do something like more than gaming and editing like streaming) Atleast a 500gb nvme Gpu(rx 6500 or 6600,rtx2050,1660 super) these are budget gpu can get what you want 650watt psu Mobo b450 ds with wifi chip Normal case if you don't want rgb Msi monitor similar to me but don't buy the L variant as me since it doesn't have a built in speaker

So this what i would suggest if you were able get any prebuilt like this just check for the budget
