<< Nothing special about that case. Standard ATX desktop case with aluminum chassis. It's expensive because it's being produced in small numbers.
All it takes to lower prices to under $150 is a major case manufacturer to recognize the potential in the desktop and slim desktop form factors, and manufacture such cases in bulk. >>
[sarcasm] Yeah, you seem them everywhere, it's a normal case [/sarcasm]
It's also expensive because it has a solid aluminum face plate that has been anodized. Quit thread crapping!
