Hi Glenn,
	I tried the connector setup that Paul suggested.  Didn't work for me.  I 
rewired the plugs so that the on off and the tally lights worked.  Will try 
to take a picture tonight of the plug and send it to you so you can see which 
wires go where.
	The cases work great.  We just left a gaping rectangular hole in the back 
where all the connectors are.
	My only complaint is that the CPU fans I got are noisy!  Any suggestions 
would be welcome!
