Japanese PC manufacturer MiniPC has brought out a new line called the GF800. The most notable feature is the support for dual displays.
Unfortunately, that is pretty much the only notable thing, as the graphics card is an Intel 945GM which is not going to pack much of a punch. Granted, most people won't be expecting a SFF to do heavy gaming, so that may not be an issue.
With a price starting out at €450 for a barebone, I think there are better offerings out there with more powerful graphics chips.
