This is an exciting new case for the Raspberry Pi 5. As we know, some casings do not allow for proper attachment of HATs when used with Raspberry Pi mainboards, or they may not close correctly when HATs are attached. However, this is no longer an issue with this case! The Raspberry Pi 5 PCIe Metal Case allows you to use PCIe HATs while maintaining a proper closure of the case. This design simplifies your setup, making it more compact and low-profile.
