Of the shelf enclosure for electronics

I am looking for an off the shelf enclosure for a few prototypes of an electrical device I am working on. So far, everything I have found has been a ugly, boring, black box. Does anyone know where I can find something better?

Rose enclosures are a small step up from boring black box.

Build one from machine building aluminum extrusions, some nice profiles can be easily customized like you describe. Some feature internal groove-fins to slide in PCB’s… 80/20, item, bosch, etc…
