Wondering about enclosures

Allo. I've been keeping an eye on mini-racks, even before the YT video, but there's something that's always bugged me.

When I picture my ideal mini-rack setup, it also includes some sort of enclosure,
- to make sure it can travel safely,
- to direct and control airflow,
- and for just plain ol' asthetics.

I've looked around all of the showcases (so excellent!), but hardly any of them are completely enclosed.

Are people just not making them enclosed, or is there some sort of group/area where some people are sharing those ideas/photos/projects?
