Shuttle has made the new KPC available. It's actually a small case the I wold consider, along with the gPC mini. The big advantage of the KPC is the price and the PCI slot. I'll sacrifice some size to get a bit of PCIe goodness, but the $199 price tag hits the right button. Considering how cheap DDR2 RAM is you can ugrade for very little. It's only a 1.8GHz Celeron, but that's plenty for light duty uses in almost any case. Of course the GMA950 graphics aren't the snappiest, though for the price it's bearable. Given the choice fo building up my own machine of going for this with a few small upgrades (RAM) I'd take this. In general I never gave Shuttle much thought as they were always priced way above my range, and they were never (really) that small (footprint-wise).
