Review on 🖥️ Geekworm Raspberry Pi 4 Case: Ultra-Thin Aluminum Alloy Passive Cooling & Heatsink Case for Raspberry Pi 4B – Compatible with Pi 4 Model B (N300) by Amanda Owens

This is a good choice for a quiet case to cool the Raspberry Pi 4. In my situation the Rpi is used as a music transport connected to a DAC. It had to be silent, i.e. without a fan. This case does a very good job of providing some protection with decent cooling. After 24 hours of operation in a 23°C room, the temperature of the Rpi board is 39°C. Assembly was easy. However, you will likely need needle nose pliers to install all of the posts as there isn't much room for your fingers. I'm using a wired connection, so I can't comment on WiFi or Bluetooth performance. with metal case.
