I have a PC I used to use as a file server and media server. I am going to try and set it up again but better. I was using Linux Mint before. I want to setup the Starr apps (Radarr, Sonarr, Prowlarr, etc).
Is it more practical to use Proxmox or Unraid? I am also consider TrueNAS but I am RAM limited (8 GB). I should point out this is fairly old hardware (FX-6300).
Proxmox is great, but if your goal is just a NAS, then you should probably go with either Unraid or a NAS os. Unraid specifically makes it pretty easy to add drives if you run out of space, and I find that very attractive as somebody who also runs all the arr apps.
