Even if you are NOT on a budget, the new M1 Mac Mini with 16 GB might be a better option if you have to work with it for many hours per day. I do not want to to do without my external display that can be adjusted in every angle and even up and down. Ergonomics is important.
I went the “cheap” route with a nice LG display. But then again, Apple’s Pro Display XDR works with a Mac Mini, too.
