An expansion card support device includes an arm configured to rotate between a closed position and an open position relative to an interior surface of a computer housing opposite from one or more interface buses. The arm is substantially parallel to the interior surface in the closed position and substantially perpendicular to the interior surface in the open position. The arm is sized so as to abut edges of one or more expansion cards retained in the one or more interface buses with the arm in the open position. The device further includes a first spring configured to rotate the arm from the closed position to the open position. The device further includes a latch configured to maintain the arm in the closed position with the latch in a latched state.
