The part that holds the monitor is on a hinge in the back, with a window latch that holds it down. It can be rotated up for access to the back of the monitor and also the PC.
Tomorrow I will start cutting some 1" x 1" spruce and start framing in the radios and such. I am just going to keep cutting strips and putting them in place with 3/8" dowels and glue until most of the open area is no longer open. The area towards the rear, which used to have a 2 meter ham radio but now is a mounting location for the Anderson power control module and also an Dc-DC 12 volt regulated power supply for the monitor will be topped off with a piece of 1/8" x 1.5" aluminum, so I will have a place to mount toggle switches as I need them.
I may also tackle the wiring of the PC itself tomorrow as it would be nice to see it boot up finally. To be honest, I need it running as the radios need some programming changes to make me happy and it would be nice to be able to do that without having to remove them and plug them into my desktop.
