A motherboard ( 200 ) including a connector ( 210 ) is attached in the chassis, the connector includes a top wall ( 211 ). The ejectors are pivotally attached to the riser card. A pressing portion ( 55 ) and a locking portion ( 57 ) are formed on two ends of the ejectors respectively. A pair of restraining holes ( 122 ) is defined in the bracket. A locking hole ( 124 ) is defined beside the restraining hole. The ejectors extend through the restraining holes. The riser card is attached to the bracket and the expansion card is attached to the riser card. When assembly, the riser card is inserted into the connector, the locking portions engage with the locking holes. When the ejectors are rotated inwardly, the pressing portions press against the top wall of the connector and the riser card is lifted.
