A few months ago i started a thread on my intended mod of a old ammo box i got from the army disposals. I cant find it so i thought i would start a new one. i wanted to build a flight case for cheap. It cost me $60 AU total and a day of working on it but i finally finished it.
Its a old 75mm motar box which cost me $30, i bought foam, hinges, wood and nails. which all cost me around $30.
Doesnt look like much room to hook the usb or rca’s up. Have any other pix of that area? Im not knocking your idea. Just saying it looks like a very tight fit.
