Oh, no, no, no, lol. Wasn't planning on using styrofoam. Was just using the pic as an example, cause of how clean they look when attached. i've seen some with shelving brackets and wanted to try and avoid that. I guess several 3-6" screws could work going through the back, was just worried if it wouldn't support the entire weight of the platform. that'll be my phase of the project for today, and get the remaining holes cut out for electrical inserts and the fog system, as well as vent spots.
