Get yourself the cheapest n150 box you can, the 4 port versions are good im case you decise to upgade and convert it to a fw later. Get a 4tb 2.5 ssd if you afford it and a chewp dual or more jbod external for safe backups.
Every year upgrade and stick to proxmox and opnsnese untill/unless you have reason otherwise.







I think you need to revisit a modern Debian 13.x distro. From install to hardware support with effortless kde plasma and a stable software level easily extensible with flatpak, it’s what Ubuntu was 10 years ago.
Anyone who says to avoid it today, especially with the AI and rocm/cuda apt packages that just work out of the box, I’m convinced haven’t considered it from an eager beginner perspective in recent form.
