Review on 📦 iUniker Raspberry Pi Cluster Case with Cooling Fan, Heatsink for Raspberry Pi 3 Model B+, Pi 3 B, Pi 2 B, Pi B+ (4-Layers, Brown) by Frank Garahana

I am well acquainted with these stacks, I have now ordered from 3 different companies with multiple clusters of more than 40 Pis. Most of these types of items aren't perfect so I'll talk about that first, I've never had a set from any company that was completely flawless. The problem here is if you need 2 you better order 3 and the company knows it. They sell them in stacks of 4. Nobody will build clusters to stack in groups of 4. They usually group them in groups of 5. The company knows this, so they know you'll order another one and eat it. Here I draw the line. Personally, I'm fine with ordering extra, but usually because I know I need replacement parts for things that aren't spinning properly, or that I'm missing, etc. If I didn't know better, my project would wait for another one order for a stack that i need "suddenly". While I like the density of the plastic, for some reason this company has a thicker material with frosted acrylic to make it last longer. Add weight, but who cares these clusters are tiny anyway. Fans could be better, but this thing came with fans, which most don't have, so it's cool that they come with fans. . You accidentally get a message that doesn't exist, or a chain that doesn't exist at all, or a nut with the wrong thread. Just weird things like that. If you need 2, order 3.
