Sorry for such a late reply, but this is not what the topic is about.
The UNVR is a multi-HDD bay machine and the OP wanted to see if UnRaid could run on such a machine. Especially the ENVR is very sexy: a 16-bay machine. If only it could be used as a NAS, instead of exclusively as a NVR.
I'm a newbie on UnRaid, and I'm preparing to hop on my first install (my rack depth is forcing me to shop around forever for an enclosure that will fit.) If ever a Unifi NVR or the upcoming UNAS can be hacked to run UnRaid, I would instantly jump on it.
