It took me about 5 hours (not really solid hours, there were lots of distractions) for the initial build last Saturday and then part of Sunday was spent troubleshooting a noise issue on the switches and mangling the case.
You didn't ask, but I might as well document these random notes somewhere.
I inverted the "dep" switch to match the original hardware. This involved a small change to gpio.c. I found this online, but I don't remember where.

I was experiencing noise on the SR switch bank. Basically everything would work with 11 switches flipped, but once I flipped the 12th I would get noise and the value would fluctuate. It was the same issue as described in this thread and had the same solution: a resistor on the SR bank with a lower value. Also in that thread is a link to the source of a test program that tests all the leds and then goes into a switch test loop. I plan on taking that code and adding command line switches so we can just jump to specific tests, but I need to contact the original author to see if we can get it up on github or something.
Physically: I had to bend the bottom switch mounts to get the board to line up with the acrylic panel. I also didn't bother with securing the board or the panel to the case: friction alone holds it pretty well. I did mount the wood blocks on the back of the board, but those blocks aren't secured to the case. I drilled a hole on the top to allow HDMI and usb power to go through and I made a cut-out on the side to allow access to the USB and network ports on the PI. It looks terrible. I may try to find a new box and use something like this to expose USB and HDMI.
Some cables like that exist but I don't expect they'd work. Most of the ones I've seen are "charging only" and don't have the wires for data. In addition the radios themselves can be quite picky about what cables will actually work with CarPlay and AndroidAuto.
USB extension cables do exist though in many different flush mount varieties. Some have HDMI or aux build in as options. I mount one of them somewhere more convenient for swapping cables.
