Upon a quick read of the features when the case was released, I fully expected it to suck very large testicles. You sound pleased with it, though. The biggest thing I felt was that it seemed the 600 did not learn much from the mistakes that were made with the original 900. And there is one picture in your review that seems to support that notion from a cable management perspective...
Sure, plenty of cable management room behind the HDD bays, but absolutely zero space for cable management behind the mobo tray (unless my perspective is off in this regard). To me, this is a fatal flaw rendering the case a non-starter for any build I might consider.
