Ah, do you feel it too? That need to own some of these, even though you have zero actual use for them.

I absolutely can't imagine what I'd use it for, and yet, my finger has hovered over "buy" many many times over the last few years
There's a 5% chance that I fall madly in love with this thing and go tinker on some project in a coffee shop every weekend... but it's much more likely that I end up almost never using it :|
Of course, then you have to ask if you need the density. There are lots of ways to put Rpi in a rack.. and this approach gives up Hat compatibility for density.
For example, I’m considering a rack of Rpi with hifi berry DACs for a multi-zone audio system. This wouldn’t help me there.
As for if that's a good use-case is a whole another thing.
