Tech Report has written up a review of the Shuttle XPC system based around the ATI Xpress 200 chipset for the AMD platform. 

Unfortunately, the box isn’t perfect. The ST20G5’s USB and Gigabit Ethernet performance are disappointing, and our sample’s VGA signal quality had some issues above 1024×768 at 75Hz. The BIOS also needs a little work, most notably support for higher HT link speeds and 0.5x CPU multipliers for overclocking. Those are all just quibbles, but their combined impact is enough to tarnish the system’s otherwise perfect finish.
