Thank you everyone for the kind words. Here is an update on the progress.
I've installed power for the console in the lower half. As you can see I built the console to be "portable". The top half is removable from the lower half making it possible for just two people to move.
Here is the lower console with the access panel for the power supply removed.
I used an 8 outlet power strip to plug in the four 12v wall warts that supply power to the four MGB boards. In addition there are two IKEA power supplies for the two LED strip lights.
Finally there are two 12v 29 amp power supplies that will power the left and right jambs of SDK's.
All the 12v lines will be routed to the upper console.
When completed the console will have just a 125v power input and a USB connection to the computer. Now there is just one switch discreetly located on the front of the console to power up.
Here is a picture of the back of the console.
The next step will be the final wiring of the upper console and reinstalling the jambs.
Hopefully there are few ideas you can apply to your own console.
