Review on GeeekPi Raspberry Pi Cluster Case with Cooling Fan and Heatsink for Pi 4 Model B, 3 Model B+ & 3/2 Model B by Matt Larsen

I actually ordered two of these because I have more than 4 Pis and it seems modular enough that I can just stack them inside each other. The current setup in the picture looks like this from bottom to top: Pi 2, Pi 3, Pi 4, Pi 4. I didn't use the heatsink kit that came with the Pi 4 as the kit I ordered already had heatsinks. And putting it all together I'm not sure if the heatsinks included in this case would fit the Pi 4. Although I have used the included heatsinks for the Pi 2 and Pi 3 and they are great.
