I hope that helps out a little about The Carrier One board!
That stuff is easy to find. As I recall, there is also something about only getting the 2GB with the quad-core processor (not a completely unreasonable choice). The tech, now that I think about it, is the probably the same as their cased cubes, since the specifications (what you can or cannot get with different models) seems to be the same. Only the form factor is new.
It's moderately clever to use an SoC/memory daughter card.
However, on the current stuff, they don't say what the SoC *is*. In theory, it could be an ultra low power x86 from Intel, but it is far more likely to be some form of ARM. I think what I was looking for--and didn't find--is one or more actual spec sheets.
Edit to add: NOW I've found some technical specs. They're in the wiki link. Freescale i.MX6, Cortex-A9.
