In the interests of authenticity for a machine like that, I'd keep it stock myself.

Now, in that connection, I have an 840av front panel that you can have for the price of shipping (Canada), as I seem to recall that yours got damaged and the one I have needs to go. I do not have an intact rear panel (in the set I had, the rear panel had been dremelled out to fit an 8100 logic board -- so it is toast).

The 840av front panel is, mind you, an absolutely ideal candidate for a retrobrite experiment.
