This case was designed to house the Commodore SD2IEC SD card adapter that is sold online by NKC Electronics. This case will allow you to mount both the mainboard and the daughter boards to keep them protected and looking stylish too!The case features openings in the front for SD card access, and (2) LED's for Power and Activity lights. You will need (2) standard 5mm LED's. On the back side, you have openings for all the ports, as well as a quick reference guide on setting the drive ID number via the dip switches. The mainboard is held in by (2) 3/8" screws in the front, and then the stand offs go between the mainboard and daughter boards, and you will use (2) 1" screws here. The four corners will need to be drilled out to allow the screw to pass through. Sorry, this is the only way I could make them recessed. You need (4) 3/4" screws for the corners. I have included the Autodesk 123 files in case someone wants to make any changes. Or, contact me with your suggestions and I'll see what I can do. Enjoy!
