Yes, stacking the Mini would be kind of an option, but it lacks a powerful desktop processor. And when you are done, your desk is covered by your Mac cluster :)
Yes, I don't get why the external enclosures for graphic cards don't have some space for disk space. But I found this link today: https://www.ifun.de/animaionic-desktop-untersatz-fuer-den-ma...
If that sees the light, that could be some improvements. If only Apple would offer the Mini in a not so mini enclosure :)

eGPUs currently are kind of a wild west of development and are still trying to decide on basic stuff like form factor and how to route USB passthroughs. That concept you linked looks like it sidesteps a lot of that by using multiple Thunderbolt connections at once, though.
That's what I mean by a more beefy model.

It seems like it would be straightforward to make it so a bunch of stuff could go in a single stack with the same footprint.
