4(Four)-Clear Stackable Acrylic Enclosure for Raspberry Pi 4, Pi 3 Model B/B+,Pi 2 Model B

I *should* dock a star for the complete lack of instructions, but my four Pi boards look so good in it that I can overlook that (especially since I was able to find some pics in a Google images search that helped). This thing seems sturdy enough, but I haven't tested it and don't plan to. It appears to be easily upgraded to handle more boards. A complaint that I've read about is that it's a pain to remove the MicroSD cards, but I haven't found that to be the case. Decent finger strength is enough to remove them, fingernails or not. That's nitpicking as far as I'm concerned, though. Finally, the cost is reasonable for folks who just want to try this Pi cluster thing with a few boards (like me). Recommended!

The spacers shown in the pictures wasn't included and screw holes location are ~1mm off from the size of the raspberry pi 4 causing the plastic stack bend and the screws are a bit too tight for raspberry 4 holes, adding tension to the boards themselves.Also the height of each layer won't leave enough space to attach the fans that are needed in raspberry 4 versions.

As other reviews have stated, the mounting screws are too large for both the acrylic plates and the pi boards, the acrylic nut that stands the board off of the acrylic plate was not provided, and the mounting screw holes are slightly displaced from the screw holes on the pi.

screw hole for raspberry pi is small. need to force screw it.

Keeping it cool

Its a beauty!
