An exemplary card mounting apparatus is for selectively mounting either of two different types of peripheral component interconnect (PCI) cards. The card mounting apparatus includes a bracket member, a receiving member, and a latch body. The bracket member defines an opening. The receiving member engages with the bracket member. The latch body hinges the bracket member and the receiving member. The receiving member is slidable relative to the bracket member, changing a length of the opening of the bracket member to allow the bracket member to receive different types of PCI card.
