I wanted a scale-able system to mount Raspberry Pis. I've seen rack mounts that hols 3-5 RPis and only take up 1U of rack space, but they waste all the space behind them.

Bear in mind my goal here is not to have the most cost efficient system by any means.





Parts List:

1U 19 Inch Rack Shelf with cutouts | Amazon Link

Raspberry Pi DIN Rail Mounts (3 pk) | Amazon Link

Slotted DIN Rails | Amazon Link

2x Bolt/Nut Per DIN Rail | from hardware store

Additional POE Option:

LoveRPi PoE HAT for Raspberry Pi 3 Model B+ | Amazon Link

Now granted I only own 3 RPis at this time, but many more may be in my future and I wanted a efficient way to rack mount many off them with out wasting slot on the rack.

This system could easily scale from just a few to hundreds.

Instructions

Attach the DIN Rails to the shelf with the bolts/nuts. Attach the RPis to the RPi Mounts, and add the POE Hats. Attach the Mounts on the DIN Rails. Put the shelf in your rack and connect the Ethernet cables to your POE switch.

Have more RPis than a shelf will hold? Just get full length DIN Rails and 2 shelves. Span the DIN rails from one shelf to the other so the rails go towards the back of the rack. Now you have trays that can hold LOTS of RPis.





I know this is overkill for my current needs, but that doesn't change how cool it is.





Happy Modding Everyone!
