I still have one *big* concern and that's the \n> center mounting screw for the front plate. The intrusion of the base \n> plate into the PCB area to accommodate this screw bothers me a lot. \n> You point out that it does not touch the PCB but it definitely \n> precludes a connector at this location which I see as a severe \n> limitation on the connector area of the front plate. I just measured a \n> right angle flight Sub-D connector and its pins protrude through the \n> bottom of the PCB almost 1.5mm.

It probably would be stiffer, although I suspect the base \n> you have just designed is stiff enough (although you might be able to \n> make the base plate lighter if the sides/back/front were integral). I \n> doubt there is any advantage to being able to insert the PCB from the \n> front due to clearances within the satellite but you can evaluate that \n> better than I. It would give module builders the opportunity to secure \n> heat producing parts such as TO-220's directly to the walls (I did \n> this quite a bit for P3D modules I built). I know that these can be \n> tricky to machine due to the flexing of the walls if they get too \n> thin.
