Learning From Other People's Mistakes
I've built a lot of cabinets. I've also seen a lot of cabinets that other people have built — some incredible, some... educational. After years in this community, the same mistakes keep showing up. Here are the seven most common ones and exactly how to avoid them.
Mistake #1: Choosing the Wrong Wood for Your Skill Level
The mistake: A first-time builder buys cabinet-grade maple because they want a premium result, then struggles with every cut because hardwood is unforgiving.
Why it happens: People skip straight to "what's the best material" without asking "what's the best material for MY skill level."
The fix: Start with MDF or birch plywood. MDF is cheap, easy to cut, and takes paint beautifully. It's heavy and doesn't handle moisture well, but for an indoor arcade cabinet, those drawbacks rarely matter. Save the hardwood for your second or third build when your skills have caught up to your ambitions.
Mistake #2: Skipping the Planning Phase
The mistake: Jumping straight into cutting wood without detailed plans, measurements, or a clear vision of the final product.
Why it happens: Excitement. You've got the wood, you've got the tools, and you want to see progress. Planning feels like it's slowing you down.
The fix: Spend at least a full day on planning before you cut anything. Draw your cabinet from every angle. Measure twice (actually, measure three times). Account for monitor dimensions, control panel ergonomics, and cable routing. A $2 pencil and a $5 notepad will save you $200 in wasted materials.
Mistake #3: Ignoring Ergonomics
The mistake: Building a cabinet that looks great but is uncomfortable to play for more than 10 minutes. The control panel is too high, too low, at the wrong angle, or the buttons are spaced wrong.
Why it happens: People focus on aesthetics and forget that this is a piece of furniture that humans need to interact with physically.
The fix: Standard arcade control panel height is 34–36 inches from the floor. Button spacing should follow standard arcade layouts (there are templates available online). The monitor should be at a slight backward angle, with the center of the screen at roughly eye level when standing. Test your layout with cardboard mockups before committing to wood.
Mistake #4: Cheaping Out on the Encoder Board
The mistake: Using a $10 zero-delay USB encoder for a build that needs to handle multiple input types, then wondering why there's input lag or compatibility issues.
Why it happens: The encoder board is invisible — it's inside the cabinet, nobody sees it. So people allocate budget to visible components and cheap out on the electronics.
The fix: Match your encoder to your use case. A zero-delay board is fine for a basic two-player setup running retro games. But if you need analog stick support, light gun compatibility, or low-latency fighting game performance, invest in a Brook UFB or I-PAC. The encoder is the nervous system of your cabinet — don't cheap out on it.
Mistake #5: Poor Cable Management
The mistake: Stuffing all the wires into the cabinet with no organization, making future maintenance a nightmare and creating potential short-circuit risks.
Why it happens: By the time you're wiring everything up, you're tired, excited to play, and just want it done.
The fix: Use cable ties, cable channels, and label everything. Route power cables separately from signal cables. Leave service loops (extra cable length) so you can pull components out for maintenance without disconnecting everything. Your future self will thank you.
Mistake #6: Neglecting Ventilation
The mistake: Building a sealed cabinet with no airflow, then wondering why the PC overheats and crashes during extended gaming sessions.
Why it happens: Ventilation holes aren't pretty, and most cabinet plans you find online don't emphasize cooling.
The fix: Install at least one intake fan (bottom or side) and one exhaust fan (top or back). A PC running inside a sealed wooden box will thermal throttle within 30 minutes. Even passive ventilation (strategically placed vents with mesh covers) is better than nothing. Monitor your PC temperatures during the first week of use.
Mistake #7: Rushing the Finish
The mistake: Applying one coat of paint, slapping on the artwork, and calling it done. Six months later, the paint is chipping, the vinyl is peeling, and the cabinet looks rough.
Why it happens: You're so close to the finish line that you cut corners on the last 10% of the work.
The fix: Sand between coats. Apply primer before paint. Use at least two coats of paint with proper drying time between each. If you're applying vinyl artwork, make sure the surface is clean, smooth, and completely dry. Finish with a clear coat for protection. The finish is what people see and touch — it's worth the extra day of patience.
The Meta-Lesson
Every one of these mistakes comes from the same root cause: impatience. Building an arcade cabinet is a marathon, not a sprint. The builders who produce the best results are the ones who slow down, plan carefully, and respect each phase of the process.
Make these mistakes on your first build? That's fine — that's learning. Make them on your fifth build? That's a choice.
