I imported a Ghost from the US, it is a great case and worth getting one if you can.
I also have a Dan A4, it is a good case but league 2 compared to the ghost for 2 reasons; build quality and CPU cooler compatibility.
The Dan A4 is well built, great quality, but doesn't compare to the extruded aluminium panels of the Ghost. CPU cooler compatibility in the Dan is poor, making run anything more that a 4 core CPU challenging. Dont get me wrong, you are limited with the Ghost too, but I run a stock 9700k in my Ghost no issues whilst max out with a Zeon 1234v3 in the Dan.
I cant think of any other sandwich cases, and they are expensive.
That said I recently built my daughter a system in an InWin A1 plus. Not a sandwich case, but a great quality case and fun to build in. A little larger but worth a look, along with the Coolermaster NC200, of similar size
