Magnetic Sliding Cover with Clear GPIO Identification
A magnetically detachable top cover enables quick access to internal components without tools. Inside the enclosure, the GPIO header area features clearly labeled pin markings and color‑coded functional indicators, simplifying wiring during prototyping and hardware integration. The sliding magnetic lid provides both convenience and protection while maintaining the clean external appearance of the aluminum chassis. This thoughtful design supports frequent hardware access in development workflows while keeping the GPIO interface organized and easy to reference during electronics projects.

Integrated Aluminum Cooling System with Smart Fan
An internal heat transfer column connects the processor area to the aluminum alloy enclosure, allowing the chassis to function as a passive heatsink. Additional active cooling is provided through a built‑in fan mounted on an internal PCB that automatically adjusts fan speed according to chip temperature. Ventilation openings at the top and bottom enhance airflow across the enclosure. This hybrid thermal design delivers stable operating temperatures during extended workloads such as media streaming, server tasks, or continuous data processing.

Rear I/O Layout with Multi‑Function Power Button
An internal interface board reorganizes audio and HDMI connections toward the rear panel, producing a clean and desk‑friendly cable layout. All ports align neatly along the back of the enclosure, creating a compact square structure with professional appearance. A programmable power button enables multiple system control functions including power‑on, restart, soft shutdown, and forced shutdown through different press patterns. This integrated control interface improves usability for desktop installations, kiosks, and embedded computing setups.
