OK, ATi is not exactly powering this contraption, but the old ATi GPU fan on the mouse certainly caught my eye. It is not the first time we have seen a build something like this. This gentleman has taken a $15 Orange Pi Zero computer board and installed it inside of an old Logitech mouse. It still ranks high on the Cool-O-Meter!
