Nice. What version of Linux do you plan to use for host OS? I self host other services but haven't tried hosting Alby hub.
Alright, I’m going to get this Lenovo mini computer, install Linux and finally self host alby hub! https://www.amazon.com/Lenovo-ThinkCentre-M700-Generation-Refurbished/dp/B077N9GCCZ

I’m not sure yet tbh, I haven’t used Linux in years. What do you recommend?
Debian is pretty reliable for servers and easy to find support.
I used Ubuntu server for years, but have used NixOS on the server for the last two years. But this would be like jumping into the deep end, so I wouldn't recommend it to start.
I'd say Debian or Ubuntu are a good place to start because you'll find lots of documentation and guides.
