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:
Nearly any SBC you’d buy would beat the pants off it. If you’re shopping by price then check out a Libre Computer Sweet Potato or Renegade, or a Friendly Elec NanoPi R2S+. They’re <=$40 and should be able to run at least the services you mentioned. If you have more budget, there are $100 mini PCs on Amazon that are great for self hosting tons of stuff, like a Bmax B1 Pro.
