Review on 🔥 iUniker 4-Layer Raspberry Pi Cluster Case with Cooling Fan, Heatsink for Raspberry Pi 4 Model B, 3 B+, Pi 3 B, Pi 2 B, Pi B+ by Mike Cassidy

Overall the case is easy to assemble. There are several comments/reviews stating that the LoveRPI POE compact hat works with the included fan kit. Unfortunately this doesn't seem to be correct. I took a picture so you can see how the fan sits on the POE hat component. The case protrusions are about 2.5cm (20mm) but should be closer to 3cm (30mm) to provide enough space to install LoveRPI POE compact cover fan. Not critical, but worth considering if you plan to use a POE hat. **UPDATE** The fan studs are too long even when using the included racks. I had to use a Dremel tool to cut the screws so the RPi that sits on top of the lower RPi would fit. There was one brace that wasn't sewn properly, rendering it virtually unusable. Luckily I found a store that sells 3.5cm (30mm) racks. They weren't cheap ($25) because I had to order a small amount.
