Sorry I went off on a big-board tangent; I saw "ITX" and thought "ATX". This mini-ITX DH61AG board likes much like an unbundled Atom board would. It meets my "half the price" benchmark! I admit over the years I've bought several all-in-one Atom- or Via-based motherboards (the latter not for LinuxCNC) for their sheer convenience. Despite that, I prefer picking mixing and matching the CPU and motherboard because of the increased flexibility. I can swap out CPUs as my hacker interests change. I just asked an Intel site for a list of compatible processors for the DBH61AG board. It looks like with a third-generation i3 CPU you can get into the mid-30w TDP range (http://processormatch.intel.com/CompDB/SearchResult.aspx?BoardName=dh61ag). I seem to recall that Ubuntu 12.04LTS, and perhaps even 10.10, has suitable graphics drivers. And never feel like apologizing for an x86 solution. It is still the sweet spot for LinuxCNC.
