Abstract: A desktop computer is provided with an expansion card/riser card module which includes a housing within which a riser card and a plurality of associated expansion cards are removably supported and electrically coupled to one another. The module, and thus the riser and expansion cards it carries, may be quickly and operatively coupled to the computer motherboard simply by pushing the module housing downwardly onto the board in a manner matingly inserting a connection edge portion of the housing-supported riser card into a corresponding motherboard connection socket. The module may be quickly removed from the motherboard simply by pulling upwardly on the module to disconnect the riser card from the motherboard socket. In an alternate embodiment of the module, this disconnection is facilitated by a leveraged removal latch structure carried by the module housing and forcibly engageable with the motherboard to lift the module upwardly therefrom.
