When building an arcade game machine, the choice of cabinet material is crucial for durability, aesthetics, and authenticity. The most popular materials include Medium-Density Fiberboard (MDF), plywood, metal, and melamine-coated boards. MDF is widely favored for its smooth surface, which is ideal for painting and applying vinyl graphics, making it perfect for achieving a classic arcade look. It is dense and heavy, providing stability, but it can be susceptible to moisture damage if not properly sealed. Plywood, particularly birch or oak varieties, offers excellent strength and resistance to warping, making it a durable choice for cabinets that need to withstand frequent use. However, it may require more finishing work to achieve a smooth surface. Metal, often used in commercial or industrial arcade machines, provides unmatched durability and security, though it is heavier and more expensive, limiting its use in home setups. Melamine boards, known for their laminated surfaces, are scratch-resistant and easy to clean, but they can chip at the edges if not handled carefully. Each material has its pros and cons, with MDF and plywood being the top choices for hobbyists due to their balance of cost, workability, and finish quality. Ultimately, the best material depends on factors like budget, intended use, and desired aesthetic, ensuring builders can create arcade machines that are both functional and visually appealing.
