I need to install my BC-250 into an ITX chassis, but I couldn't find any existing projects, so I made one myself. It consists of two parts that can be snapped together to form a frame - you screw the BC-250 into it, and then screw the entire frame into any PC chassis with standard ITX motherboard holes. I used M3 screws, and it worked great. If you're using water cooling, the frame also supports backplate installation. Please use PETG for printing

Please note that you need to first remove three screws and take off the IO panel, as some of the holes in it are used for the frame itself.
