A gaming terminal includes a housing defining an exterior of the gaming terminal. The gaming terminal includes one or more displays disposed along the housing. The one or more displays are adapted to display, in response to a wager, a wagering game. The gaming terminal also includes a substantially closed interior enclosure disposed within the housing. The interior enclosure includes walls formed from electrically conductive material. The interior enclosure can be substantially closed. The gaming terminal further includes one or more signal-emitting components disposed within the interior enclosure and emitting a level of electromagnetic signals. A transmission of electromagnetic signals from the substantially closed interior enclosure is less than the level of electromagnetic signals emitted from the one or more signal-emitting components.
