Review on 🔳 GeeekPi Raspberry Pi Cluster Case Stackable Rack Case with 120mm RGB LED Cooling Fan 5V for Raspberry Pi 4B/3B+/3B/2B/B+ and Jetson Nano (12-Layers) by Sidewinders Rains

I ordered this 12 layer cluster case on Thursday and it arrived on Saturday so very happy with the fast delivery. Parcel arrived in good condition and all items were well packed. I chose this cluster case because I needed to reorganize my many Raspberry Pis that I use for various projects. I initially considered a rackmount solution, although that ultimately won out as I run some of my Raspberry drives off external SSDs (instead of a micro SD card) and the compatibility of the acrylic layers with various hardware made this case stand out. I was able to mount the Raspberry Pi on one level and then mount the corresponding SSD, originally in an external USB enclosure, on the next level to connect via the same USB cable. Although this required removing the SATA USB adapter from the external case, it didn't make much of a difference. I ended up being able to fit 7 Raspberry Pis in separate cases and 5 SSDs in separate cases. USB cases and combine them all in one well-organized and lightweight case. Active cooling was another major reason why I chose this case. I don't currently use POE hats on my drawings, but the fact that there is space between each layer to add them if I ever decide to do so was another huge plus. The overall build wasn't as bad as I thought it would be. would. All the necessary screws, standoffs and nuts were included (and there were quite a few as they give you an extra amount of each to account for variability in user configuration i.e. more SSDs or more Pi than I used.). All of the laser cutting and etching was precise and very rewarding, and aligning all 12 layers and the three fans to get the second side wasn't really all that difficult as they are a "comb" to get the 12 layers one at a time to hold and move. I would say the biggest problem in the whole process was peeling the backing paper/film off the two large sides of the acrylic. I've probably spent as much time on this as I've spent connecting all the devices to 12-layer boards. The paper just kept tearing and I had to shoot inch by inch. Maybe it would be easier if I tried warming it up with a hair dryer or something, but I managed to get it all off in the end. The last image attached shows the case with all 7 Pis running the RGB fans. The lights are cool, of course, but that definitely wasn't a selling point for me. Since this "rack" is in my basement network/utility I'll probably turn them off as no one will ever see them and it's just a waste of power. Finally, just for clarification, a couple of pictures I've attached of an octopus with cables sticking out the side/top are power supplies with a switch and then micro hdmi male to female hdmi adapters with 4k hdmi plugs. I like on/off adapters to easily toggle individual Pis. I then connected the HDMI connectors as I usually use the Raspbian GUI OS on each Pi and only ever access it remotely via VNC. So the dummy stubs ensure the desktop loads properly on boot/reload since I didn't have real monitors attached to each Pi. and/or 2.5" SSD/HDD.
