Here is what I have in mind so far (note I *REFUSE* to buy mail
order/online so this is what is in my local MicroCenter):

CPU (Ryzen 3600 $200.00 65 watts w/ fan):

Motherboard (x570 AMD 4 ATX $170):

Power supply (850 watt $130 ATX):

Case (minitower ATX $75):

RAM (16 GB DDR4-3200 $70):

Reuse keyboard/mouse/video card/monitor

Total: $645

##  Personally I agree with everything you have here.  MB maker is a preference so I'm not spouting mine. :)
However, even when you settle on graphics and storage media, check the power consumption.  I've been going lower and lower on my PSUs.  I'm down to using 550-650W now and will, in time, probably, go lower but with a higher efficiency something in the 80-Gold or higher.
Also, you don't need to buy a PSU with 800W.  It's just overkill.  Calculate (there's a lot of online calculators) how much your machine will draw.  Take that and add 33%.  Otherwise, you're spending extra money for nothing.

I'm running an Nvidia 1070ti, AMD 2700X, 16 GB RAM, etc.  At the wall, my peak seems to be only using about 430W (???).  Of course, my storage is M.2 NVME... 1TB chip, so I really don't have a lot of draw anywhere on the box.
As always, have fun with it. :D
