Buildapc

I have been teaching myself Linux on really old hardware. I am looking into building a new system so I can learn SDXL and maybe mess around a little with LLMs.

I have been reading as much as I can, but get a lot conflicting info. Ideally I would like a build that I can get started with, without being at bare minimums if possible. Just best value at a realistic starting point. Willing to save up more if it will save me from waiting forever while my PC is maxed out. With options to expand easily as I go. Don't mind using used hardware. I have also read some about cheap enterprise hardware being an option that can expand easily?

Any help would be awesome. Thank you in advance.

P.S. Happy New Year! Wishing everyone all the best. After the past few years, we could all use a better one.
