Yup. 94.8mm x 100mm for the board outline that fits into the PCB slot in the socket. Copied from previous review. Trust but check. Checked! It is exactly what you would expect from photos. I put a 94.8mm x 100mm board in it and it fit perfectly. This is the perfect case size if you have tall components and also want to keep the board size within 10cm x 10cm to get really cheap boards from China.
