Below is a video demonstrating all the steps for Full Kit assembly. The 54 minute video covers all the major steps, required tools, and tips when building. So, if you're on the fence, or just curious what building a cabinet is like, this will help. The video is a compliment to the PDF manual. The pdf manual is the most accurate and up-to-date assembly guide.
Here are other mini arcade and arcade builds that you can reference. There are similarities between many of these designs not just in mechanical assembly but also electrically.
