Introducing the Heavy Metal Keyboard (HMKB), formerly known as Simple Keyboard (SKB). The HMKB is a mechanical keyboard enclosure made from bent sheet metal. It is available in various sizes, including HMKB-60, HMKB-65, HMKB-75, HMKB-80, and HMKB-95. Each size comes with different keycap sets such as GMK Dark, GMK Ashes, Dolch, GMK TARO R2, GMK Nautilus R2, and more. The HMKB is known for its sturdy construction and sleek design.
