Review on 🔨 GeeekPi Raspberry Pi Cluster Case, Stackable Raspberry Pi Rack with 120mm RGB LED 5V Cooling Fan for Raspberry Pi 4B/3B+/3B/2B/B+ and Jetson Nano (8-Layers) by Zack Block

Great case. This gives a slot of attachment options. I built one with 4 shelves using 4 Raspberry Pi 4s and the advanced features they contain are lifesavers. I've used it with a SanDisk Ultra Plus 128GB with no problems. I built a second 8 shelf case to easily use with 4 Nvidia Jetson Nanos. Shelves have pre-drilled nano holes. (The Nanos have a tall heatsink so you will need to install the Nano on every other shelf (8 shelf model for 4 Jetson Nanos). PLUS if you are using a Jetson Nano the SSD holes remain open and you can place your SSD mount on the underside of the shelf.
