The problem is quantity and market size.  The market for PC motherboards
that fit into standard cases is so large that the quantity of scale is
enormous.  When your start talking about PC-104 boards the market is so
small that they must stretch the life of a system for years in order to
recover development costs and to deal with the relatively small quantities
(100's instead of 100,000's).

So if you want a COTS, small-footprint motherboard capable of fitting
inside a standard instrument package, you are going to pay a fair bit for it.

BTW, this is some of what we are discussing on the avionics list.  There
are some who are working on hardware.
