It's designed to fit in a 3U Eurorack row. There's multiple instances on the site of someone or some company adapting a desktop unit to fit in a Eurorack case, presumably so that the user doesn't have to take up extra room putting the desktop unit somewhere separate, or so that they don't have to have multiple power supplies and worry about a separate box. It's eurorack mainly for the sake of convenience.
