Has this ever happened to you? You buy a used mobo, and it comes shipped in a box. That's a good start. (I've had a mobo sent to me in a padded mailer before. I even received a CM-300 in a large padded bag once, but I digress...)

You open the box, and it's well packed inside with newspaper, or whatever. That's good too. But when it comes to the mobo itself, do sellers believe that if they don't "pin it down" with layers of parcel tape, it will somehow break free of it's padded box and escape?
