Ethernet connection (upper left on rear panel), power regulator (upper left), Rpi computer
(below terminal strips) and URI audio/logic interface by DMK engineering (DMKeng.com) below the Rpi.

Added 1-9-18 rack box showing 5 Allstar nodes. Upper left is WA6IBE Allstar/EchoLink in development, upper right is WB6DAO Hub, lower right is WB6DAO-R repeater & WB6DAO-R EchoLink.
Bottom middle is 8 port switch (so I don't have to bring more than one Ethernet connection into the rack) Upper middle is the 12 volt to 5 volt regulator array, one for each Pi and one for switch.
