Is there going to be any kind of support under the control panel? I'm assuming from the profile you're basing it on this cab:
Do you have a type of paint picked out yet? Trying to find a truly metalic silver might be hard.
Support has been taken into account. On the Cab pic you see how relatively short the part is where the controls will go? First of all: the parts on the control box itself will fit exactly on there. It "slides"on if you will. Then -invisible to the eye- once finished I have got two wooden bars that attach to the control box on one end and to the bolt on the bottom of the monitor supporting shelf on the other end. The weight of the monitor will definitely keep the control panel steady and the weight of the control panel will balance the entire cab better. On top of that; I will have two large 90 degree iron corners and magnetic clips to attach the control panel to the "main cabinet" to make it rock solid.
It is loosely based on the MVS-4 you linked to. Obviously I need a bigger CP for the trackball and to accomodate for more buttons.
The marquee area seems pretty small. This is kind of ironic since the MVS cabs have a pretty big area for the marquee. Obviously it's done now, but that's going to limit the size of the artwork that will show in there too.
It is very small. It is about 6 * 30 inches. Although I am happy with the width, the height could be bigger, I agree. I will make the best of it and see what gives. It had to compromise somewhat since it is already a big beast. But let's hope some good art will compensate for size. "Size matters not" as some say

About the paint; I have a good source and I know the paint I want is available. The edges do not have a groove in them for T-Molding. This was done deliberately since I will be using -and you guessed it) chrome.
Thanks for the feedback. Much appreciated!
