I just received and unpacked mine. I love the size and the interchangeable panels. Now, the only thing that would make it better is if I could easily buy replacement panels - in particular I'd REALLY like an option to buy separate plain blank panels. No vent holes, no window, just formed metal. That would make it easy for cutting in my own mods and whatnot. Being able to buy an additional windowed panel, or vented panel would also be nice, but the blank would be my favorite option.
