        Ya know, that's really an interesting idea.  Actually, it'd be
just a wall wart with an IEC input connector (instead of the various
country mains connectors) and a couple tapped holes to bolt the thing to
the rear panel.  Actually, I have seen little desk top enclosed supplies
that could probably be bolted into a cabinet in this fashion.  It'd be
great, though, to have a 12 VDC 500mA unregulated supply that you just
bolt to the rear panel, and have it cost $5.
