So I have more JAMMA games then I have dedicated cabinets to stick them in and for this reason, I mount most of my boards on a backing piece of hardboard, trying to keep the stack as small as possible.  This aid with storage when not in use. When it came to CarnEvil, I wanted to remove its hard drive, and replace it with a compact flash. Unfortunately, this has the Compact Flash sticking 90° up off the main motherboard, not flat at all. A bracket  was designed to rotate the card to a flat position, using a short IDE cable  This frame resolves the height problem and ensures no damage to the board  when its stored on the shelf. The CF adapter is held on by one screw using the slot and bump to hold it in place. The voids in the CF placement area are there for relief for solder point below the PC board and to insure the board lays flat. The largest  hole is for the IDE cable to snake below the frame.
