Raspberry Pi 4-Layer Cluster Case with 3007 Fan (Brown)

Very pleased with this. I have one of each of the model B(+)s (1,2,3 and 4) Raspberry Pis and even though it was not mentioned in the product description, was so pleased to find that in addition to my 3B+ and 4B, my 2B+ also fitted in this (at the bottom in the picture).Unlike a lot of other reviewers, I have an excess of screws, nuts, etc so maybe the supplier have taken note.It is a nice touch including a mini screwdriver as well.The only issue I have had is that the nuts on the very top do not fit on the risers very snugly so the top layer wobbles if I pick the stack up by it. However this is easy to resolve by inserting small washers underneath.As others have said, the instructions are very small.Despite these two small issues, overall I am very pleased with this as will form a great starting point for my Pi stack.

Quite fiddly for the older fingers but 4 fans, 2 sets of 4 heatsinks and the wee rack - very good and a good end product. I used the pins to give the fans a slower speed as I'm not intending to run the cluster hard. As has been said, you need a phone to enlarge the instructions. I also had the fan label facing down as I wanted to push air down onto the heatsinks.

Nice bit of kit, looks good and does the job. I like the inclusion of fans.I didn't give it 5 stars because the instructions are printed quite tiny -- and more clarity on which screw to use where would have been appreciated.But once you work it out, very nice. If you buy multiple kits, they can be stacked partially or wholly together into one unit, too.

A few minor issues with this product.1) Instructions are a bit unclear in poor English - how difficult can it be to get an English speaker to review the instructions prior to printing?2) The connectors for the fan power are a bit flimsy and you need to be careful when connecting them.3) Fan Fixing Bolts: The ends of the bolts are dangerously close to the underside of the Pi above them. The instructions are very clear about this but shorter bolts would be better.Other than that this is a good value product and seems to work well once assembled. Works equally well for Pi 3B and 4B in the same case. Fans are not too noisy however l'd be interested to see how long they last if run 24x7x365. They do the job and reduced the CPU temp of my Pi's by nearly 30 degC.I'll be buying another one.

I went looking for cases for the pi 4, and separately for heatsinks and a fan. This package includes everything in 1 little box. No need to hunt around for different sets, which is a huge bonus.This DOES work for the new Pi 4 4GB model, which was recently released, but I'll put 1 minor issue with this set (let's be honest, I'm just nit-picking here), I had to use one of the spare large heatsinks (designated for the CPU) for the memory, as the smaller one barely covers 1/3 of the memory.Stress testing the CPU, I hit 53C max, which is far lower than running without one, so it has most certainly done its job.For my old Pi 3, it's perfect, all the heatsinks are adequate and the included fan keeps things nice and cool.The only MINOR suggestion I'd make to update this box is to include 4 more "cpu" heatsinks to cover the CPU & ram chip (for the pi 4 4GB version). I'm not sure if the 2 or 1 gig versions have a large ram chip, so I can't comment on that. If you're not using all 4 racks, the spares are more than adequate to cover everything that's needed.

Needed to stack 7 pi's (so far) for a project. This does great (ordered 2). Only dropping a star on value for money as it comes with fans and heatsinks I dont need (already have a fan on POE header and can't fit all the heatsinks with it on), a version without all the extras would be great.I've since realised I need a platform alongside each pi for this project, so I'm having my own sheet cut to give me space on each level but this got me started.

Build quality, design & instructions all very good.Beware that the first generation of Raspberry Pi did not have through-holes so will need something else, like PCB edge clips and need new holes to be drilled

There’s something a little bit exciting about assembling one of these things - or at least when you’ve finished as you get a sense of building something a little wacky.But that said I can almost guarantee that at some point you’ll realise you’ve either started with the wrong bit or done something the slight wrong way round! So read the instructions. If you can.The instructions are on a small card - great for the planet but terrible for your eyes. The picture of where you attach the fans is almost pointless and you’ll end up looking it up elsewhere. Actually the fans are quite exciting - I spent about five minutes neurotically contemplating which way round to put them, wondering if I’d be cooling the board or pushing warm air onto it instead. (I don’t think this neurosis is limited only to this kit - I had the same thoughts with other PIs which I stacked). Maybe this doesn’t matter so much anyway because PIs seldom run hot even if you’re doing something pretty intense.Overall though once you’re there (and it can be a bit fiddly at times) you end up with something that keeps them all in one place and might impress someone who likes that sort of thing.
