I think most people find that putting the Roon core on a suitable machine gives a pretty much bullet proof experience. Running it on anything less is just asking for trouble.

Given the cost of a NUC vs historical cost of Sooloos Hardware cores (just giving the relative sense of affordability) it makes it much of a no-brainier.

I think in hindsight supporting Roon core on NAS units will be viewed as probably a bad idea (given the cost of Other options these days)
