My personal thought as a lurker trying to learn enough through osmosis to start her own set-up is that hardware concerns are fine as long as they still relate to self-hosting in some fashion. “What hardware setup would be good for beginners looking to self-host a Google Drive alternative on a budget?” is self-hosting, fine, and the type of thing I would bookmark for my own reference. “Anyone have advice on cannibalizing an old laptop to DIY a mini PC?” would really not be self-hosting, even if your plan is to use the resulting mini PC to self-host a server.
I’d also be inclined to treat posts that are off-topic but have a selection of informative high-effort comments by locking them and sharing them to the appropriate community for further discussion there vs. removing them entirely.
Which is to say, yes, I like your proposed revision.


!askelectronics@tchns.de is a bit more low level than is most common, but may still be worth including on the list.
