There's the whole PC/104 consortium.  3.6" x 3.8" (90 x 96mm)
modules that stack.  Plug a CPU module and whatever peripheral
devices you need into a unit.  Lots of manufacturers support
it.  Start at: http://www.controlled.com/pc104/consp1.html .

A specific manufacturer is Ampro (norther California), www.ampro.com,
that makes PC/104 moduels along with their own line of small single
board PC computers.
