I think a start would be providing an extra screw hole in a standardized place, so that case manifacturers can design for this, instead of putting the card between 2 plastic clamps. A problem here would be length differences in cards though. But I think that it being in the middle of most long cards, and at the end of the smallest card isn't the craziest idea.
