A modular wall system having an integrated air flow path that provides cooling of heat generating component housed within the system. In one embodiment, the modular wall system includes wall vertical brackets that create one or more vertical flues, as well as ventilated base cabinets that are configured to direct the flow of air over component stores within. The top of the wall system may be vented allow to heat rising through the flues to vent into the surrounding atmosphere. The bottom of the base cabinets may be ventilated to allow air to enter the interior cabinet from the surrounding environment. The rear of the base cabinets may be open to the flue to allow air to flow from the interior of the cabinet up through the flues. The doors of the base cabinets may also be ventilated to provide additional air flow.
