This is pretty much a Wendell and Qain question, if they would be willing to give one of these a spin http://linuxgizmos.com/tiny-fanless-mini-pc-runs-linux-on-quad-core-amd-soc/ and see how it compares to the other low end hardware that you guys have used for these types of builds.
The specs of the quad core version don't look too bad, only thing is it looks like the storage has to either be mSATA/mPCIe based or external since SD cards don't like the abuse a normal drive will take.
