A small home nas or a plex could easily do what my fileserver 'Enigma' does.
But I built Enigma in 2001. Granted she's had her upgrades and grown from 1tb (princely back in the day!) to 25, but it's the same server.
This is how most of it goes. You see a tech with a giant rig doing something that a smaller commercial unit does nowadays? That didn't exist when the custom rig was built. That's why the rig was built. To fill a need you can't commercially.
Anyway that's storage, my fuckoff ram server runs the nagios and home automation servers and is used to spin up test vms for work : P
