I just got mine in, the "non-retarded" version.

One box had a crushed corner but both cases survived intact. Externally it is just another boring beige box, begging for the spraycan. Internally it is aluminum as advertised and partially toolless. It has a steel bar running top to bottom over the motherboard area to help it stay rigid. That bar can be removed by taking out two screws but I'd just as soon leave it in there. The aluminum is thin so it should be easy to mod. There is not much in the way of air vents in front, just three tiny slits towards the bottom of the face and of course the opening underneath the face. Not much of a problem for a cooler running system but it can be for some. Rear fan grill needs to be cut out for airflow. Still a decent deal because the faults can be easily fixed and I don't see many other cases selling for that cheap, aluminum or not.
The best deal IMO was the SkyHawk from Dealsonic, back when they had it for $25 plus shipping. The aluminum was much thicker (thought would be tougher to cut) and it was a natural finish and had better ventilation. However that deal is now dead. Other cheap aluminum cases like the other one here in Hot Deals for $35 shipped are IMO not as good as this one because they don't take standard fans. Newegg occasionally has a SkyHawk with the same chassis as the one from Dealsonic for only a few bucks more, but IMO it looks strange with that funky side fan cam. Cool idea though, to be able to reposition the fan.
