Review on iUniker Raspberry Pi 4 Case with Cooling Fan and Heatsink - Simple Removable Top Cover for Pi 4 Model B/ 4B (Model M) - Black by Carlito Tardy

So you should know that this case is perfect for Pi4. Mine slid right where it belonged and all the connectors fitted together perfectly. You won't want to use this case when adding a HAT to a Pi, but it's perfect without one. The small included fan worked great and kept my HASSIO setup running 24/7 at low speed for weeks with no heat issues. The kit comes with all the parts you need, unlike most things that come with screws they don't just come with the cheapest option so they don't immediately start removing the heads when you spin them. There are 4 small clear rubber tabs that act as feet to hold it in place and they work great. I had to figure out which way to go when installing the board, but that might just be me. There is nothing to complain about on the set itself. I have metal cases for my other Pi builds but wanted to try something different and I'm not disappointed. For a good non-HAT case, this is a great little option that includes a fan and good airflow design. I'm happy with it and will use it again next time I use plastic instead of metal.
