I have an old i3 PC that I’d like to useas a NAS but I’d prefer to use FOSS instead as realistically I don’t know even this is even the solution I want to go with and would rather avoid dropping a lot of money on something I may change.
EDIT: Thanks everyone for the suggestions. I will be bookmarking them all. Probably give TrueNAS a go first since I’ve heard of it before. (I think from LTT.)
Proxmox
Edit: Installed as the hypervisor on bare metal and then whatever you want to try out like OMV, Plex, jellyfin, syncthing or cloud software in an LXC or VM
A hypervisor is a great option because it lets you test a bunch of different software solutions to see what works for you, and it’s a great way to learn. Proxmox VE is just a great software too.
Turnkeys are super useful too
