This is a tested and working project

This project provides you with a set of small stereo speakers which can be directly mounted in a spare 5.25" drive bay of a computer. It is primarily intended for retro computer systems, but it could be used with modern systems if you were inclined to. Full instructions on assembly and case are available in the GitHub.
