@Charles: Gluing is barbaric. What are you? Some kind of a mobile phone manufacturer? 
Let's consider a slightly different design. The bottom half is a slide-in tray type holder of the card. It has guide rails on both sides for the top half. Buffers to stop the top in the right position. Recesses for the studs on the top half to lock the case vertically at the port end. And a buffer at the back side of the DB9 connector to lock the card in place from one direction. Both halves end in the plane of the DB9 connector's shield at the I/O end. The top half, as the actual "I/O shield", has the necessary cut-outs and recesses for the Joystick Connector, the Reset Button and the Audio Jack. It either covers the bolts of the Joystick Connector or protrudes between the bolts and the connector shield and towards the PCB and the other electromechanical assemblies as much as possible to lock the card in place from the opposite direction. And the whole cover is closed and locked vertically by a sub-M2-sized countersunk, anodized black screw from the bottom, between the Joystick Connector and Reset Button.
The case marking, obviously, should read as CAE in the current design, and NAE V2.0 in the possible design for the older cards.
