Found this Intel/SiS based mini-itx motherboard, D201GLY.
According to this benchmark it seem to perform pretty well, even in multimedia applications at a very low power consumption (around 20W without a HD), It´s performance is a lot better than Via based platforms and it´s price is very low, at less than $70 including a celeron CPU. For mor information about performance see this, http://www.imedialinux.com/intel-d201gly-power-consumption-and-performance.html
Since I do not have a motherboard with sis integrated graphics I cannot verify how well this chipset will perform as a LMCE MD.
Anyone tried running an MD with sis graphics?
Since this graphics chip display media in an overlay window it should in theory allow us to run at least UI2 without alpha blending.
I believe (if this chipset perforam well enough) we can build a fanless MD for less than $250 including enclosure, soundcard, picoPSU, AC-adapter.
