New PC Campaign

I moved from Cape Town to Port Elizabeth a few months ago. But i had to sell my pc to cover the fuel cost.

Im teaching myself to program and use AI programs,so i can take care of my family, working from home,but my laptop isnt up to the task.

So im in need of a pc, that can be upgraded later on.

Im hoping for a razen 5 or i5 atleast 9th gen cpu and motherboard. If possible a 8gig gpu to help with rendering. And atleast 16 gig ddr4 ram.

I dont mind a 2nd hand pc. It doesnt have to be new.

I enjoy fixing computers and working on electronics. 

If i do get the funds to build something, i will make sure to get something that will work for a few years.

Thank you to everyone thats willing to help.
