OK, there are ways and ways and here's something I need feedback on:

One of the biggest problems with EUro are the many many module widths.
 Not a problem for the modules - the varied widths are a real plus in
that regard.  The problem are the rails.  If you don't use a pre-fab'd
IEEE standard railing system, such as Vector and a bunch of others
provide then you are forced to have some sort of mounting surface
manufactured that has that long row of 5.o8 mm spaced m4 holes.  

xtremely costly.

OK, let's make that easy and say we have to use one of these pre-made
systems.  One way we could really cut costs if instead of having to
buy a duplicate power system for each box, if a central power unit
could be used to power multiple racks. There's one way.  SO the first
rack with the central unit may cost a little more,  but the second or
third unit would be much less expensive.

But there's another idea which would make it make it very affordable -
having a open frame.  No box around, just rails with a single panel
that holds the power bus.  It's got it's problems, but it's got some
real benefits with it.  Assuming the rack will be mounted in a chassis
that is enclosed, could this be a viable alternative?

By looking as my component counts on my modules you know I'm not one
to cut back of circuitry unless it's functionally sound to do so.  But
we're talking about single row mounting systems that wouldn't breach
the $150 barrier.

Your thoughts are appreciated.
