I worked at a place that tested software releases on a VM of every supported operating system, including OS X. We didn't have any Apple hardware, because no one wanted to deal with that, but someone had brought in the chassis of an old Apple computer and the host computer was inside it. We didn't run it by any lawyers or anything, but as far as we could tell, running OS X inside a computer that had all of its guts replaced was entirely within the license requirements.

IANAL but I think you'd be fine as long as you placed your NUC on a Mac Mini or maybe a closed Macbook if your hardware has a larger footprint.

> use and run one (1) copy of the Apple Software on a single Apple-branded computer at any one time.

Note that you do have to be careful not to stack multiple Macbooks when you do this.
