I had my 2012 and 2020 (M1) Mac mini in a vertical stand.
I’ve re-used that stand for the new Mac mini though, obviously, not vertical as the M4 mini is more stout.
In my tests, the effects seem negligible. I just don’t like wasting things — and it looks neat. Nonetheless, yes, yes, I haven’t settled yet on physical placements of the hub and external drives. The difficult balance of form and function.
New gen Minis show the hot air coming out the right side when viewed from the front. If this is the case, they should work best when oriented vertically on the side, so if the bottom is facing out like in the photo you'd want the ports on the right side and the front to the left.
ETA: I believe this would put the power button on the bottom right facing out, unless I'm misremembering where it is on the new Minis...
Apple’s animation isn’t completely clear — no pun intended. The flow is front half of circular grill intake and rear half exhaust. And while I’ve only had it speed up to a noticeable level under absolutely full workload, that little blower does an impressive job.
This is likely how Apple designed it for server farms. Easier access to power button and better cooling

My OCD is triggered because the 'Mac Mini' text is upside down!
A nitpick, that’s more of possible
OCPD.
OCD is different:
People with OCD often have an inflated sense of responsibility, meaning that they feel responsible for things that are not within their control.
Fears about making mistakes in OCD involve obsessions about making any type of mistake, either by negligence, error, or random chance, and causing a negative impact on one’s life or the lives of others.
The quote is good, and I linked as a citation, but there’s not really an ROCD (as a subtype).
OCD — linked more appropriate extended definition — is, at its core, a feeling of worry, concern, accountability. Even OCPD isn’t a subtype, it’s more of a notable variation as the obsession aspect is significantly enough different.
I have both OCPD and OCD -- and have improved substantially though not shaken them entirely. To finish light-hearted, here’s a little OCPD self-ribbing: Me leaving a room, turning the lights off, and not all of the light switches are down… Then returning:
