Pros

• Solid aluminum case with excellent finishing. Every exit hole was clean and properly centered over every port. Nothing blocked up.
• Excellent quality plastic top and bottom finishing. Bottom includes pre-installed feet.
• Build-in heat sink for the processor. Conducts heat away from the processor and into the entire aluminum case.
• Extremely easy to insert the Raspberry Pi 4 and fasten case and Pi together.
• Insertion and removal of the SDXC card through the case is the best I’ve ever seen and experienced in a case.
• Processor temperature in this case is a good 30°C less than running it in the official Raspberry Pi 4 case. As far as I’m concerned the official Raspberry Pi 4 case is a waste of your money.

Cons

• Can’t use a flat cable with a standard header to plug into the the GPIO port. The distance between the posts used to hold the Pi on that side match the holes, but are too thick and as a consequence too close together.
• CPU temperature is not as low as I had hoped. The processor runs about 10°C cooler than allowing it to run opened up. I had expected around 20°C.

Overall

If you want to buy one for yourself then here’s the link: https://flirc.tv/more/raspberry-pi-4-case

The problem with the GPIO flat cable connector is with a continuous flat cable. I’m sure if you’re using a subset of the GPIO pins and using individual wires bundled together you won’t have a problem. I’m in the process of looking for a special flat cable with a header to use with the Flirc case.

I paid $12 for the case. I’ve certainly spent more for less. I know that the official red-and-white Raspberry Pi 4 case is $5. But I still say, considering how much heat the Raspberry Pi 4 dumps out, that you’re better off with a Flirc case than the official enclosure. Even with heat sinks attached, the official enclosure has no venting; the system will just cook itself inside the official case unless you remove the top like I wound up eventually doing.

The Flirc case is not the one case to rule them all. If I need cooling beyond what Flirc currently offers then I’m going to have to use an active cooling solution, i.e. something with a fan. But for the time being, using this Pi as an official itty bitty computer, the Flirc case is superb.
