I've spent way too much $ on this project --- would be a shame if I leave it in a naked state, but I am really reluctant to make a custom enclosure and have someone machine it because it's more $$$. So in I opened Digikey catalog, picked a box that roughly fits the main board, loaded the 3D model in CAD, put some holes in the box, and voila:

Now I need a drill press... better a mill. Or I could use my old good flush cutter and tear that damn piece of plastic off.
