nice! I should pay more attention to current events I guess.
Next, please tell me they came out with a OSX Server replacement that handles computer sign-on without needing some $10/month MDM service.
Pretty easy to get minis or studios into racks with 3rd party mounting solutions. You do need to pay attention to power needs (low, but you need AC power, not DC) so might need a PDU in the rack to convert / distribute depending on how many you're planning to put in each rack.
Indeed, it’s not out of reach and compute density is higher than the Mac Pro with Minis (even the core i9). M1 / M2 is vastly higher.
