GeeekPi 6-Layers Cluster Case Rack Case with Heatsinks Stackable Enclosure for Raspberry Pi 4/3/2 Model B,Raspberry Pi 3 Model B+ (Clear)

So the quality of it is okay.Assembling the rack with Pi on each level is effortless and quite easy. However mounting the rack together is ... a little bit challenging. You'll figure it out and have it fully assembled in 10 minutes though.The seller should improve the instructions because it's not that clear, but only fee choices and reasonable person definitely can figure it out.P.S. Don't forget to remove the two side cover on each board, or the stack would look horrible.

TLDR: Extremely simple and quick assembly, can't possibly ask for anything else!- Took only as few minutes per RPi (remove from existing case, add heatsinks, mount to plate, add to stack); I didn't time it but less than an hour total for sure for the 5 mounted RPis pictured.- Included heatsinks are a nice touch!- Came with extra screws, standoffs, etc.I do not plan on overclocking, using GPIO, adding hats, or using otherwise any other features, which makes this really simple setup by far the absolute best value. Because of this the small standoffs aren't an issue for me as noted in other reviews.I am also unsure of the issues with the assembly instructions (unless it was worse prior to my purchase). Assembly was easy and painless. However, get a little creative orienting pieces if you need to get things together easily. I found it easier to mount the standoffs to the RPis first, and then attach them to the acrylic plates.

This is a great way to stack five RPI3 or RPI4's. One nitpick is that the brass standoffs between each "layer" or "story" of the tower is only 2.5cm long, which doesn't leave enough clearance between layers to access the GPIO pins; I only run my RPI's in headless mode and when I need to debug an individual board before I have networking setup, I use a RS232-to-USB dongle with wires that connect to GND TXD and RXD pins on the RPI.One workaround is to use TWO 2.5cm brass standoffs instead of one to get added length. Otherwise I think this is a great product!

I wanted to consolidate with a taller tower and this was a great option. I was glad to see it come with heatsinks for all my pi's, that was a nice added value. It's been in service more than a month now with no heating or other issues.

Like the device. Compact size to do tradeshows for looping video playout on multiple TV's. Biggest problem is finding a small nut driver to tighten screws..

You’ll need very small fingers and great dexterity to put this together. And really good eyesight and lighting. Whatever the benefits, this is not a good use of your time.

The media could not be loaded. I had another almost identical "case" and this almost matched exactly. I used temporary double-sided Gorilla tape to attach the bottom plate to an 8-port PoE switch, and zip tied two 92mm fans to the side. I used PoE adapters on the six Raspberry Pi 4Bs. All that's missing in the short clip are the ethernet cables.

I had to buy additional spacers as my Pis have POE Hats and NVME bases etc. It seems their are not really any options if you want more than a basic Pi setup.
