I would say yes, because as is the real niche communities dont have the size for larger discussions.
Mainstream communities e.g. about global news already have a decent size. And in many ways it doesn’t make much of a qualitative difference if there are 500 or 10.000 predictable comments. But many smaller communities are still mostly propped up by a few power users providing the majority of content which is not ideal for many reasons.
Mini PCs with a n100 or used office PCs are probably not that much more expensive and a much better alternative, if your goal is to run windows on them and you don’t already have the Raspberry Pi lying around.
