I have the first Internet Window prototype built up. I used a laser cutter to cut a frame out of 3/16 inch thick cast acrylic. This frame is just intended to hold everything together enough that it's a single unit instead of a mess of wires. I also had to solder the power cables down.
The final version will have a frame that can be wall-mounted easily. It will also have a smaller interface board that has the correct connectors for the power cables that come with the panels. In the meantime, I will continue to document this project on Hackaday.io.
