A cabinet system comprises a chassis having a plurality of openings, a plurality of modular doors, and at least one radio frequency system. Each opening has removably attached chassis-hinge portions on one of two edges. Each modular door comprises an outside surface, an inside surface opposing the outside surface, and door-hinge receptacles on at least two edges. The door-hinge receptacles receive door-hinge portions. Each door-hinge portion is positioned in a respective door-hinge receptacle on one edge of the plurality of modular doors and is configured to mate with a respective chassis-hinge portion on the one edge of one of the plurality of openings so the mated chassis-hinge portion and door-hinge portion form a hinge to rotatably attach the modular door to the one of the openings. The radio frequency system comprises electronic components attached to the inside surface of at least one of the plurality of modular doors.
