The mini rack is pretty decent, but I wish that the size decided was a 12" or so rack, so that more computer hardware could fit without the struggle.

I’m sure more stuff will be made the accommodate this scene though.

Centralization is a weakness

While I agree with the basic premise of this, I think this is all-the-more a good reason for design solutions around this problem to be discussed so that more competitors can exist. If the fediverse is to expand, there needs to be easy non-technical ways for users to start up a multitude of instances. More of these types of services actually reduces centralization, in that sense.
