Creating the perfect arcade cabinet involves a delicate balance between form, function, and feasibility. The optimal size and weight are not arbitrary; they are determined by a series of critical, interconnected factors that ensure a satisfying and practical user experience.

First and foremost is User Ergonomics and Comfort. The cabinet's dimensions must cater to the average human form. The control panel height should allow for relaxed shoulders and a 90-degree elbow bend. The viewing angle to the monitor must be comfortable to prevent neck strain during extended play sessions. Furthermore, the distance between buttons and the joystick's resistance are subtle details that impact gameplay comfort and are dictated by the panel's size and layout.

The second crucial factor is the Hardware and Component Selection. The type and size of the monitor or CRT tube directly dictate the cabinet's width and depth. Similarly, the choice of internal components—a simple Raspberry Pi versus a bulkier PC—affects the required internal space and, consequently, the overall weight and dimensions. The inclusion of additional features like light guns, force feedback steering wheels, or a subwoofer will further expand the cabinet's footprint.

Third, the Choice of Materials plays a significant role in both weight and durability. While heavy-duty MDF (Medium-Density Fibreboard) is the standard for its stability and authentic feel, it contributes significant mass. Lighter alternatives like plywood or even acrylic are sometimes used, but they may compromise on the classic heft and durability. The material choice is a direct trade-off between authenticity, weight, and structural integrity.

Another key consideration is Portability and Accessibility. A cabinet destined for a private home may not need to move often, allowing for a larger, heavier design. However, if the cabinet needs to be moved through standard doorways, up stairs, or transported in a vehicle, its dimensions and weight become paramount. Designing for disassembly or incorporating casters can mitigate portability issues caused by a large, single-unit design.

Finally, the Available Space and Location for the cabinet is a primary constraint. The cabinet must fit its intended environment, whether it's a dedicated game room, a living room corner, or a commercial arcade floor. This available space sets a hard limit on the maximum possible height, width, and depth, forcing designers to optimize the internal layout to accommodate all necessary hardware within these spatial boundaries.

In conclusion, determining the optimal size and weight of an arcade cabinet is a multifaceted process. It requires a holistic approach that prioritizes the player's physical comfort, accommodates the necessary hardware, selects appropriate materials, considers real-world portability, and respects the physical constraints of its final location. A successful design harmonizes all these factors to create a machine that is both a joy to play and practical to own.
