When building an arcade machine cabinet, choosing the right materials is crucial for durability and performance. The most popular options include Medium-Density Fiberboard (MDF), plywood, and metal. MDF is affordable and easy to work with, making it a favorite for DIY enthusiasts. Plywood offers better moisture resistance and strength, ideal for long-term use. Metal cabinets, though heavier, provide unmatched durability for commercial arcades. Each material has its pros and cons, so consider your budget, skill level, and intended use before deciding. By selecting the right material, you can ensure your arcade cabinet stands the test of time.
