NAS in this context is more about home server then an actual plain network attached storage.

I usually call mine NAS too, despite technically using it more for selfhosting - and basically never mounting it's data volumes. I think this applies to almost everyone using them nowadays, which is also the reason why the pre built ones are less and less relevant - because they always have super conservative CPUs (which are more then sufficient for a NAS that's actually used as a plain network attached storage - but severely underperforming if the user wants to run services on it.)
