death star panels

Hey guys, need help to identify some props. I'm pretty sure the cube are hand made but I'm pretty sure those containers are something you can find, but I'm no container expect :) But maybe some of you are.

Similar to what we're doing with our Blade Runner Bathroom, sections of our new facility will feature Death Star panels in their various styles. Though they'll be fiberglass, we sort of like the idea of doing the "vents" and "grills" as actual, functional elements because our air lines and dust...

What are the dimensions of the death star wall panels and any tips how to make them, I would like to make them life size and add LED lighting to light up the panels.
