Clueless!!!
Might I make a suggestion. Build yourself a cnc router, or cnc a mill, or build a plasma talbe, or any of the above. You may find that all of your time is taken up with mods, improvements, servos, steppers, control systems, drive chains, ball screws, software, cad, cam, drivers or any combination of the above. Game case fabrication may pass before you get over the cnc bug!!!
Just a thought!
