The Armor Case "Block" is your ideal choice when it gets really hot. This high-quality, aluminium-based case protects your Raspberry Pi 4 B not only against exterior shocks but also against interior excessive heat development due to its channel milling. That's why it is perfect even for extreme settings and environments. Furthermore, this case does not need more space than the Raspberry Pi 4 itself and can thus be integrated inter alia in already existing projects.
