Ah ok, so basically a case that allows vertical orientation of the motherboard. I must admit that I haven't seen many cases like that although it is a good idea in theory. The only other one that I know of that allows that kind of orientation is the Fortress from Silverstone as well and it's also a pretty bulky case. Any particular reason that it must be this way? There are a fair number of cases that ventilate really well without vertically mounting the motherboard. Another option would be a custom case from someplace like Mountain Mods but it won't be cheap.
