I have to say that the project needs to find a route that is as cost effective as possible or you guys will never recoup your investments. Go all DIY on the phase-1, if the board fits a micro atx as planned getting a case won't be a problem. Get it out - Make it simple. Then go to phase 2 and get everything in the wedge computer shape you want all along for the mass. x8 sound like a bad idea, acorn electron vs bbc micro and commodore 16 vs plus 4 is two good examples why. I'd gladly buy a diy phase 1 and put it in a case of my choosing since well. that's what I have wanted all along.
