Anyone tried the ASUS DiGiMatrix? The SiS chipset seems to be well
supported in Linux. It even appears to have component HDTV output on
the back of the box. The bundled TV/FM tuner card is probably only so

interesting, if pricy. It has the decided advantage of actually being
in stock somewhere ($319 at NewEgg).
