So… a Steam Link?
No, the Steam Link couldn’t actually play games natively and could only stream them from another system, this would be able to play independently of another PC but still requires an external screen and controller.
I think you are thinking of the steam machines.
Link only streamed.
This is a Steam TV.
Similar form factor, but no network or remote PC required.
