Help me build my first pc

I have a gaming laptop that is a fucking workhorse but I’m looking to upgrade

Budget:
Im gonna save up and buy all the parts slowly and have them build it at my local microcenter so I don’t accidentally fuck something up but preferably not more than 4k. I know pcs don’t last forever but I rlly wanna invest into something that can last me ya know

What I use it for:

1. I’m a 2d/3d artist and I’m wanting to start delving into solo deving my own game so it needs to be able to run blendr and godot pretty well. No crazy rendering tho, I stick more with low to medium poly shit.

2. I also edit on davinci and currently my laptop can run davinci as long as I don’t add to many effect so it needs to be able to do that as well

3. I don’t play many heavy fps games but being able if I wanted would be nice

Also storage is importsnt to me because pulling files into davinci from a fucking drive is probably not helping my speed. Oh and ig a good color monitor but I do have a Wacom that I do most of my shit on.

Oh and being able to run 3 monitors would be nice. I’m thinking my main monitor and then a vertical monitor and my Wacom cintique on the side. Hopefully I didn’t forget anything and hopefully that’s not too large of an order lol
