A plurality of electronic components 110 are preferably placed within a sealed electronics compartment 125 which forms a part of the closed loop for the circulating gas 70. The electronic components 110 may comprise one or more of the following: power modules, video player, electronic data storage, microprocessor, satellite/wireless receiver/transmitter, and timing and control board. At least some of the electronic components 110 may be in electrical connection with the displays 30 and 31.

One or more fans 90 may force the closed loop of circulating gas 70 over the electronic components 110. While shown with two fans 90, this is not required. Additionally, while shown pushing the circulating gas 70 over the electronic components 110, this is not required as the fans 90 could also be positioned to pull the circulating gas 70, or several fans 90 could be used in a combination push/pull of the circulating gas 70.
