For the box, I would use wood glue and a nail gun. The glue is what creates the bond, nails just keep it together while it dries. We did an experiment back in my car audio days to prove it; we glued two pieces of mdf together in three configurations and then tried to break them apart. Glue only, glue and nails, and glue and screws; from strongest to weakest in that order. The screws just gave you leverage to snap the piece, Anyways, my point is just go with glue and the nail gun. As for the console, you can really use whatever you're comfortable with. I have seen people use MDF, Fiberglass, or sheetmetal and they all came out good.
