I used to run a Pluto MD on an EPIA M10000 with the onboard video, using a custom-built kernel and VxMC accelerated graphics drivers, and it was still BAD.
Last week I got an Nvidia FX5200 PCI video card for the M10000, and it's now running the LinuxMCE UI2 with blending very nicely... so my recommendation would be: M10000 as a small and silent MD - definitely, onboard video - no way, LinuxMCE Hybrid on the M10000 - not if you can avoid it.
