When we get it all finalized maybe a custom case of metal would be best?
This outfit even has a free CAD tool called Protocase Designer:
Protocase Incorporated - Custom Electronic Enclosures for Engineers and Designers
I'm not sure if it would be a good idea for a couple more revisions, but it might be good if there is enough demand.
I am a big fan of a nice metal case. (also, you could put a big fan in a nice metal case, oh no, it is pun time!)
It looks like silkscreen and colors are options, but totally unnecessary for people just into functionality.
