Not the person you responded to, but I'll give my unsolicited advice: I switched to Unifi NAS. QNAP has had a lot of security nightmares, and a bad habit of EOLing devices.
The best option might actually be using an old workstation and going with something like TrueNAS, but I enjoy the convenience of a purpose built box.
One big difference between Unifi NAS and something like QNAP or Synology, is that the Unifi NAS only does NAS work, it doesn't run containers or "apps". You need separate compute if you want to run containers.
