Raspberry Pi 4 Model B 7-Layer Dog Bone Stack Clear Case Box Enclosure Also for Pi 3B+ 3B 2B B+ A+ B A …

Looks cool. Sturdy as hell. Isn’t crooked. Buy it.

It's a pain in the butt to get the plastic protector off of the parts, but it does keep them scratch free during shipping. I'm running a Hadoop training cluster on 7 pi's and this was perfect for that.DO NOT THROW AWAY THE PACKAGING UNTIL YOU'VE GOT IT TOGETHER. There are **small** plastic screws that you will need that are wrapped in a little packet. I threw them away accidentally and had to dig through my garbage can to find it.The price is a bit higher than I think is warranted when you consider the manufacturing cost of the components, but it's got a quality look and feel to it and if I needed another I would purchase again.

The only problem with this stack is that it doesn't allow for connection of GPIO Expansion boards out of box. So no POE boards, you would have to get longer standoffs to be able to do that. There are other dogbanes that allow pi boards to stack with access to GPIO for less cost. Other than that design is good.

Great dogbone case for my grid of pi's.

The parts are good quality and fit well. It worked well with Raspberry Pi 2 and Raspberry Pi 3, but did not work with the Banana Pi.

Nice setup for a bunch'o'pi. But with no feet, the bottom gets little air from below. So I had to elevate the assembly.

It will take a few minutes to get all the pieces aligned but once you get the first ones done, you can move quickly from there. Make sure you get fins for your processors or they'll overheat, even with the open format.

Peeling the paper is finicky.
