An integrated front projection system has a housing assembly, a projection assembly, and an expansion assembly. The housing assembly includes a frame having a front surface that provides a front projection screen and contains other modular components. In addition, a projection assembly with a movable arm may be included, having a storage position and a projection position, and to which the front projection head may be coupled. According to one aspect, the projection assembly is modularized and has a plurality of easily replaceable component modules coupled to the housing and which operate together to project an image onto the front projection screen. According to another aspect, the integrated front projection system further has an expansion assembly coupled to the housing. The expansion assembly includes an expansion slot formed in the housing and electrically coupled to a display controller in the projection assembly and expansion modules coupled to the expansion slot. The expansion modules operate to enhance functionality of the display controller.
