I would like to host a small instance for me and my friends (<10). I was thinking about buying a small single board arm computer to host it. What would be the minimum system requirements for this and do you have recommendations besides the raspberry pi.
Kind of a big jump from a pi but I believe Intel NUCs come in single board arm configurations
I find that ebay used desktops and laptops excellent for this kind of thing. You can find used Dell Optiplexes for under 100 USD on auction, if NUCS are too expensive.
