I've used nothing but Thinkpads (T2x-series and T4x-series) in my ham 
station for the last ten years, and the shell of the DB-connectors IS a 
chassis connection. That's what I've always used, and it works quite 
reliably.  It has been my experience that if I do need to plug something 
into one of the DB connectors that a retaining screw on only one side is 
quite sufficient to hold it in place.

BTW -- when equipment is properly built, the connector shell IS bonded 
to the chassis.
