I've got my RPi 4 set up as a file server with a small "internal" SSD drive hooked up to it via a SATA-to-USB cable. I'm using the Flirc case, and it all has a pretty small footprint on my table. Though I'd still like to find a little rack or a shelf unit that I could sit it on, maybe with the drive underneath.
I've see the acrylic "dog bone" stands, but it doesn't look like a 2.5" SSD or an RPi in a case could fit in those.
What are some other solutions people have come up with?
