I’m a complete noob with: A computer with 4GB of RAM 1 tera of storage A computer from 2014 Free time Computer with a dead battery
I’m trying to selfhost files with nextcloud and imich (idk if I have writen it correctly)
English isn’t my first language btw


Your computer very likely doesn’t need a special distro for low end devices yet. A common distro like linux mint will do fine, and that’s probably the best choice if you’re new to linux.
Edit: if you only want to host stuff on it, and nothing else, maybe that yunohost people recommended can be a better choice
