In-vehicle entertainment (WE) monitor systems can be reconfigurable and modular to improve heat dissipation characteristics and to enable separate removal or installation of one or more parts within the WE monitor system without affecting the rest of the IVE monitor system. A modular system for providing in-vehicle entertainment to passengers on a commercial passenger vehicle includes a main housing, a peripheral housing, and a display panel that are separately removable or installable. A main printed circuit board (PCB) in the main housing is electrically connected to a secondary PCB in the peripheral housing via the first data cable and the secondary PCB is electrically connected to the display panel via the second data cable in a series configuration.
