A mounting structure includes a central airflow pathway for a first dedicated flow of ambient air with electronic equipment located along the same. One or more side assemblies are attached to the mounting structure and include a cover, a display layer located rearward of the cover, an illumination device for illuminating at least the display layer when operated, and a side assembly open loop airflow pathway for a second dedicated flow of the ambient air. When operated, the electronic equipment provides functionality other than operation of the one or more side assemblies. The central airflow pathway and the side assembly open loop airflow pathway of each of the one or more side assemblies are fluidly separated from one another. ## Claims ### Claim 1 A display assembly comprising: a mounting structure comprising a central airflow pathway for a first dedicated flow of ambient air;
