Mark,
It would seem from first glance that strain relief tied to the underside of the laptop would be the way to go. Replaceable cable tie wrapped to the underside of the laptop would keep things neat while in the case and easy to replace when the cable has been overstressed. The cable will then also keep the card in place. You might even be able to add a loop in the cable then tie wrap to the extender/adapter and then to the bottom of the laptop to lock everything together. I am always one for having spares so if you are going to keep the laptop I would look into having a spare card slot (they usually just plug into the board inside the case), a spare cable and spare card adapter. If the laptop needs to sit on a flat surface, add a few stick on feet. You can get a variety from any hardware store.
