Features:
1. The surface is easy to produce a dense and firm protective film, which can protect the substrate from corrosion, and is light and durable, with strong wear resistance and rusting.
2. The outer casing can be equipped with a cooling fan. The hollow design makes the heat dissipation more effective and protects your motherboard.
3. The outer casing and the main board are closely fitted, the various interfaces are highly consistent, the hole position is accurate, and the demolition is easy.
4. The outer casing of the aluminum alloy is slotted and does not affect the WIFI/Bluetooth signal transmission.
5. High hardness, high pressure resistance, metallic luster, not easy to rust. Aluminum alloy material is more conducive to heat dissipation.
