WTB: Project Enclosure for RGB scanner build

[KGB_Productions]

Currently working on a RGB 20k scanner build and looking for a nice project box to put it all in....needs to be at lease 12in.X10in.X5in. (lXwXh) I was hoping to find a nice extruded aluminum case BUT i cant seem to find one that large. Im sure that somebody knows the correct place to go..........

Hopefully I can find something like in the pic but larger

Thanks,
