It's been a long time since I've updated, so you could be forgiven for thinking this project is dead. It is not. My personal life has been demanding and I haven't had the time or inclination to work on this. Part of that was hitting a wall with the enclosure. I felt I lacked the skills to pull off an adequate DIY enclosure and I lacked the funds to buy a pre-fab one. I really liked the Retex Abox series, even though they are a bit small. I considered splitting the project into a controller and display, but the cost of buying the boxes would be absolutely prohibitive.
In all honesty, I was feeling quite down about the whole thing, until I found another project's blog. I really liked the design, modular layout and rather simple construction. I finally felt like I had a path forward. I reverse engineered his design and mocked it up in SketchUp. I really like it and I think I can do it, wish me luck.
