A method and apparatus for expanding the circuitry of a circuit board, such as a computer motherboard. The apparatus can include a riser card removably coupled to the circuit board and having a plurality of expansion slots for receiving expansion devices. The riser card can include a connector for receiving a second riser card having further expansion slots for removably receiving additional expansion devices. Accordingly, a single riser card can be connected to a circuit board that is installed in a chassis that can accept no more than one riser card, and a pair of such riser cards can be stacked, one upon the other, on a circuit board that is installed in a chassis that can accommodate stacked riser cards.
