Actually, this case makes me want a minimig! :-D
Btw. since you are open for designing custome cases, there are always "caseless" systems around that one can design cases for, there is definetly a market for custom cases.
For example, I have a gumstick LCD pack
http://www.gumstix.com/images/LCDPAck-assembly.jpg that is sold just like that without case, my plan is to build a micro-laptop, just need to find a suitable USB micro-keyboard and a good casing :lol:
