## Description

A premium aluminium enclosure for the Raspberry Pi 4, featuring a stripe-grooved design on both top and bottom halves that enlarges the heat dissipation area for effective passive cooling.

Precise cutouts provide access to all ports and connectors, with a reversed GPIO slot and openings designed to minimise WiFi and Bluetooth signal interference. Key Features Stripe-Grooved Design – Enlarged surface area on top and bottom for fast passive cooling Inner Heatsink Pillars – Uni-body design conducts heat from key components to the entire case Fanless Operation – Completely silent passive cooling with no moving parts Precise Port Cutouts – Full access to all connectors including USB, HDMI, Ethernet, and power Reversed GPIO Slot – Access to GPIO pins from the rear of the case WiFi/Bluetooth Friendly – Openings designed to minimise wireless signal fading Specifications Compatibility – Raspberry Pi 4 Model B Material – Aluminium alloy Cooling – Passive (heatsink pillars + grooved body) Note: Raspberry Pi 4 is not included.
