My local ham group has actually built two multi-TICCs on request as a 
fund-raiser, and we could probably be talked into doing more.  Given 
four TICCs, Front Panel Express sheet metal, an RPi, various cables and 
connectors, etc., and a little bit for the volunteers, it's not cheap by 
ham/hobbyist standards, but a bloody bargain by professional ones. :-)

If anyone is seriously interested in having one built, contact me off 
line and we'll see what we can do.
