What type of computer setup would one need to run ai locally?

Not sure if this goes here or if this post will be hated upon? but i want to host ai like llms and comfyuis newer models locally but im not sure what type of setup or parts would work best on a possible slim budget? im not sure either if now is the time with inflation and such.

I dont have a price in mind yet but im wondering how much it would cost or what parts i may need?

If you have any questions or concerns please leave a comment.
