Create a Micro-ATX/Mini-ITX/Flex-ATX (doesn't matter as long as it's *TX) motherboard that takes the EOMA68 CPU card and breaks out all the required ports and takes power input (4-6V or 10-14V DC, and/or ATX power, and/or PoE). This would have the advantage of fitting into a standard ATX chassis which means re-use of off the shelf components for building things like small rack-mount servers. http://www.wired.com/wiredenterprise/2012/01/wimpy_nodes/
The Carrier Board project above is within the ITX board dimensions, allowing the mounting within an ITX case using conventional hardware. It can be powered from both an external 6-12vdc power sources, or through an internal onboard molex header allowing the use of a standard ATX Power Supply to provide power with included jumper.
