A housing assembly for an integrated display unit is provided. The display unit display unit comprises an open loop pathway for ambient air, a closed loop pathway for circulating gas, and at least one electronic display. A first and second horizontal member extend between a vertically extending first and second side member and are secured within a first channel and a second channel. The first and second side members form exterior side surfaces of the display unit to define, in part, the closed loop pathway. The first horizontal member forms an upper surface of the display unit and the second horizontal member forms a lower surface of the display unit to further define, in part, the closed loop pathway.
