Would not recommend, given my UDMs logs are full of random errors and issues all the time, which seems "normal" for them. Not to mention pretty ui but weird bugs and strange behaviours - plus ui looks great but feature wise it sucks.

Next time I upgrade I'm just buying mikrotik again...

Fair enough, but I've used thousands of Unifi devices at work and at home and I don't recall ever having to look at the logs. Obviously YMMV, but their NVR storage has been rock solid.

Yeah UNAS is one option I'm exploring. But the only thing I'm wanting on top of all that is something like Plex or Jellyfin and I don't know how well it will play with a UNAS if running on a external server

It’ll be fine. I eventually managed to get a Mac mini to work nicely as a headless docker + VM server. It’s a moster, and averages just 7w of power draw. A neat saving for a solar house (the old nuc 9 was 70w).

It works fine as a NAS, but you need to run Plex on a different server.

You can't run Plex directly off the device like a DS224+ would.

A N100 or other type of cheap hardware will be much better than the synology.

That + a Jonsbo N2 is a great option, it's what I run.
