This industrial looking Raspberry Pi case that’s been going around was purpose built to mount on a DIN Rail. (Some home solar/battery wall power systems probably have such a Pi monitoring the energy.)
What to do with these palm size, rack mountable boxes? what about a ZinoRack networked Zynthian demo, playing a massive orchestrated piece live using 16 or more cores (too bad there’s no bus system like in Euro Racks?)
Imagine the steel rail is mounted on a wall and the LCDs are vertical. Can power through Ethernet run a Pi 4?

This little 7x9cm box accommodates an audio hat, and ribbon connected 2.2" no touch TFT it was designed for (with OK 320x240 res, 4X the pixels of that 1.8" listed in the web config menu) There’s a ILI9341 SPI driver that yields up to 60 fps by only drawing changed areas of the frame through accessing the BCM2835 ARM Peripherals controller registers (sounds a little scary) There’s limited real estate for additional connector, all USB MIDI seems more tidy.
The rack mount details that none of these enclosure sellers are mentioning.
