Aluminum vintage-looking case for Raspberry Pi/rpi "pifi"?

I'd like to add a small screen and a not-ugly case to my raspberry pi streamer (uses volumio). The only thing close to the aesthetic I'm thinking are the sold out ones here. Not sure if aluminum or steel is more commonly used.

Does anyone know of a company/source for the sort of machined metal style cases?

There's probably a proper word for this aesthetic/era but something (anything) like this:
