In computing "Pro" is not the opposite of "Consumer".

Putting aside the fact it is a marketing label, "Pro" usually means "designed for work" while "Consumer" (in this context) means "doesn't need a special environment".

In computing the distinction is primarily noise, power and cooling requirements.

If a computer is designed to use home power and is quiet enough to use without annoying people and doesn't require specialist cooling then it is a consumer device, even if it is used for work.
