1. A base chassis assembly for an information handling system allowing user replacement of touch-actuated icons and speaker comprising:
a base chassis top cover joined to a base chassis bottom cover to form the base chassis assembly housing a motherboard with a hardware processor, a memory, and a power source, where the base chassis assembly has an opening sized to receive a replaceable icon and speaker module to be operatively coupled to the motherboard via a motherboard-sided module connector disposed in the opening;
the replaceable icon and speaker module having a top acrylic layer forming an icon panel including a plurality of touch icon zones, each of the plurality of touch icon zones including a first icon of a first plurality of icons for a first touch icon zone, the first icon formed from etching a first array of light prisms in the top acrylic layer bottom surface for refracting visible light of a first color emitted from a first side-mounted light-emitting diode (LED) to the top acrylic layer bottom surface;
the first array of light prisms having a refractive index for refracting visible light of the first color emitted from a first side-mounted LED at a first determined angle from the top acrylic layer bottom surface to illuminate the first icon in the top acrylic layer; and
a capacitive sense circuit board for sensing a first user touch at a touch sensor for the first touch icon zone to actuate one of the plurality of touch icon zones, and identifying a user input associated with the first user touch based upon identification of the icon illuminated in the first touch icon zone.
