It appears that Dell might be adding a new case design to its lineup. Designed by Matthew Ritter, of Alienware fame, the case is definitely on the unusual side. Dell has taken quite a few steps outside of the 'beige box' approach in the past couple product generations, but this is a bit of an outlier.
The new series is going to be dubbed the XCS, though the specifics of hardware are currently unknown. It is speculated to be an Intel/ATI lineup, which would be in line with some of the Computex cross-marketing between the two companies with the upcoming Core 2 Duo release.
