I've got two large pieces of scrap black laminated MDF (3/4") that I am willing to give away for free to any interested parties. You'd have to come pick up the pieces from my apartment near downtown Chicago. The pieces were supposed to be side panels for an arcade cabinet, but they broke at the top during shipment. There is a lot of usable wood there, for control panels or they could easily be cut down to be used for front and rear panels.
I'll be watching this thread. Hopefully someone will take this off my hands so I don't feel like I'm wasting it by throwing it away.
