Great case, but despite the many options for installing a micro power supply on the back, the round pico power supply is not compatible. However, the metal is not very strong and malleable enough. I was able to go up a size to fit the connector. Use toothpicks to do this gently, then file and rasp to remove any sharp edges. You can use a glue gun to properly attach the connector, double check, but glue gun glue is generally non-conductive and should be a good option for this. Make sure the glue is at the correct heating temperature. Yes it's a bit of a hack but the overall size is good and it worked fine for what I needed (OPNSENSE firewall). That being said there are probably better options if you can afford a little more space I don't have.
