Since not everyone will be doing PC cases, and since this is a real can 
of worms, I think I'll leave this as an exercise for the builder.  We'll 
probably make small runs of JANUS, so once a suitable bracket is located 
and some boards are actually fitted, we can solve this.  There are lots 
of companies happy to make custom PCI brackets.  The real trick for this 
will be to know the relationship of the board edges to some reference 
location on such a bracket.  Maybe this is a good exercise for the Alpha 
boards?

Have fun in the Great White North.  Say hello to the MacKenzie brothers 
and watch out for Strange Brew, eh?
