I’m using my old desktop from 2010. There’s no such thing as a server that can “do it all”, but any computer from the last 10 years would probably be a fine place to start. The more you do, the more likely you’ll be to hit some sort of performance limit, and by that time you’ll know more about what you actually want.
In short, find old cheap/free hardware and start playing around.
It’s called a crisp because it’s crispy (at least to my knowledge).
