Review on 🖥️ Black Raspberry Pi 4 Aluminum Case by Geekworm - Heavy Duty Cooling Metal Housing with Heatsink Pillar - Compatible with Raspberry Pi 4 Model B Only (P173) by Tim Thuss

Bought for a Pi 4b (4GB) to use the pi hole ad blocker. It's about the lightest load you can give the Pi. I even went as far as overclocking the CPU as I don't need factory speeds just for the pi hole. Even after that, this puppy will keep you warm. We're talking about 50°C - enough for the Pi-Hole server to issue a warning with every login. I ended up putting a 140mm fan next to it, which brought the temperature down to around 32C, which is much better and the system no longer gives any warnings. . That being said, I bought this as a fanless passive solution. Had I known the temperatures are hotter than my other fanless Pi cases, I might not have bought it. On the other hand it was easy to put together and looks like it. No branding, no stickers. looks unassuming and clean. I'll leave the 140mm fan in place for now, just concerned with the extra power and noise.
