Yep. There are a few cases that as built around the same layout - I have the Aerocool DS Cube and everything except the top, front and bottom plastics is identical. No bad thing - the DS is a cracking little chassis.
In fact, you'd really have to go of your way to ruin a case based on the same skeleton, so we should take our hats of to Deepcool for trying damned hard to do just that. It is hideous.
It is NOT steampunk. Never has been, never will be.
Finish the roof in a faux rivetted boiler plate effect and you'd be on your way but, as it is, it's just sad.
