Not sure I understand this distinction.

What is stopping you using Mac with MacOS?
Most likely wanting to run Linux natively. Only M1/M2 can fill that role with Asahi, and still not with 100% hardware compatibility.
On the flip side, an M4 mini is cheaper, faster, much smaller (with built in power supply) and much more efficient. Plus for most applications, they can run in a Linux container just as well.
It’s not great as a headless server.
With full disk encryption enabled you need a keyboard and display attached at boot to unlock it. You then need to sign in to your account to start services. You can use an IP based KVM but that’s another thing to manage.
If you use Docker, it runs in a vm instead of native.
With a Linux based ARM box you can use full disk encryption, use drop bear to ssh in on boot to unlock disks, native docker, ability to run proxmox etc.
Mac minis/studio have potential to be great low powered home servers but Apple is not going down that route for consumers. I’d be curious if they are using their own silicon and own server oriented distro internally for some things.
