Computer chassis having flexible card guide for expansion card insertion and removal

The present invention provides, in a computer chassis containing a substantially planar removable expansion card therein, the computer chassis having an opening therein allowing access to the expansion card, a plane of the expansion card substantially parallel with a plane of the opening, a support structure for the expansion card and a method of supporting the expansion card. The support structure comprises: (1) a guide body movably attached to the computer chassis adapted to assume an engaged position and a retracted position and (2) guide projections on a surface of the guide body, a recess between the guide projections adapted to receive an edge of the expansion card when the guide body assumes the engaged position, the guide projections thereby supporting the expansion card as against a force normal to the plane of the expansion card, the guide body assuming the retracted position to allow the expansion card to be removed from the computer chassis in a direction normal to the plane of the expansion card and transverse to an orientation of the guide projections.
