I don’t think I’ve ever met someone who got into making a home server and started out with a full-tower ATX case or a NAS enclosure. It always begins with repurposed desktops, old laptops about to be taken to pasture, or leftover office machines. However, what almost always happens is that those home servers begin accumulating responsibility. One drive becomes three, and three becomes six. Suddenly, this box in the corner isn’t just the “Plex box” anymore, and it begins holding backups, personal data, family photos, documents, and things you’d genuinely be upset if you lost.
