[Soekris] Securing the PCI slot cover for an internal USB connector

I've a net5501 and have gotten a pci slot case cover
with USB plug and cable for exposing the internal
USB connector to the exterior of the case.
The problem is that because there's nothing
plugged into the pci slot, the right hand
side of the pci case slot cover is free to move;
enough so that it can be lifted and
freed of the restraint placed on it by the circuit
board. This frees the right hand side of the case
slot cover to wiggle around, making
plugging and unplugging a USB device more difficult
and possibly endangering the electronics should the
case slot cover contact the electronics on the board.
I believe the right solution is to build a protrusion
onto the inside of the case to prevent the right hand
side of the case slot cover from moving upward.
This modification might be accomplished in the
field with a judiciously placed drop of epoxy.
I rejected a screw assembly similar to that which
comes with the cover supplied with the case because
of the difficulties involved in tapping threads
into the case slot cover.
The kludge I'm actually using is to place a styrofoam
packing peanut inside the case on top of the
USB plug. It prevents the case slot cover from
moving far enough upward to be free from the
board, is compressed enough that
it's not likely to move, is non-conductive
should it dislodge, and I find that it makes
it much easier to properly align the case
for closure. (!)
Anyone else have any experience or comments
regarding exposing the internal USB or serial port?
