Is an ARM mini PC with only 2GB RAM and 16GB storage worth buying?

My current setup is an old MacBook woth 2 external HDDs, and I am almost happy with it, for now. I just saw this mini PC on Amazon and I am considering buying it, just to try out a new thing. I think it is cheap (~22 USD).

What I am worried about is that this much memory and storage might make it almost unusable. I was thinking of hosting some minor services, like remark42, shynet or vaultwarden. What else do you think I can host? If my mind changes, I will also try it with a desktop environment and try to connect it to my 4K Android TV.

Here are some specs, if you don't want to visit the webpage:
