Building an arcade machine is a practical project for anyone who wants the feel of a classic cabinet without relying on aging commercial hardware. A well-planned build combines carpentry, consumer electronics, arcade controls, and emulation software into one durable system. The key is to define your goals early: a compact bartop machine, a full-size cabinet, or a four-player unit for family rooms and events.
TLDR: A reliable home arcade machine can be built for about $450 to $1,500, depending on cabinet size, screen quality, controls, and whether you use a Raspberry Pi, mini PC, or refurbished desktop. For example, a two-player bartop cabinet using a 24-inch monitor and Raspberry Pi often lands near $600, while a full-size machine with premium controls may cost twice that. Expect the build to take 15 to 30 hours if you are comfortable with basic tools and software setup. The best results come from budgeting carefully, choosing legal game sources, and testing controls before final assembly.
1. Decide What Type of Arcade Machine You Want
Before buying parts, choose the cabinet format. This decision affects nearly every cost and design choice, including monitor size, wood requirements, number of buttons, and computer power.
- Bartop arcade: Smaller, cheaper, and ideal for apartments or desks. Usually supports one or two players.
- Full-size upright cabinet: Closest to the traditional arcade experience. Requires more space and stronger materials.
- Pedestal arcade: A control panel with no built-in screen, usually connected to a TV. Good for multiplayer setups.
- Wall-mounted cabinet: Space-saving but more difficult to service and mount safely.
For most first-time builders, a two-player bartop or upright cabinet is the safest choice. It keeps wiring manageable while still delivering an authentic experience.
2. Plan the Parts List
A dependable arcade machine needs more than a screen and buttons. Below is a realistic parts list for a standard two-player cabinet.
- Cabinet material: MDF, plywood, or a flat-pack arcade kit.
- Display: 22-inch to 32-inch monitor or TV with HDMI input.
- Computer: Raspberry Pi, mini PC, or refurbished office desktop.
- Controls: Two joysticks, 12 to 16 action buttons, start buttons, coin buttons, and wiring harnesses.
- USB encoder: Converts joystick and button inputs into signals the computer understands.
- Speakers and amplifier: Small powered speakers or a compact amp with cabinet speakers.
- Power strip: Internal surge-protected strip for the monitor, computer, and audio hardware.
- Cooling: One or two low-noise fans if the cabinet is enclosed.
- Finish materials: Paint, vinyl wrap, T-molding, primer, screws, brackets, and wood glue.
If you use a pre-cut cabinet kit, the woodworking stage becomes much easier. If you cut the cabinet yourself, prepare accurate plans and double-check all dimensions before touching the saw.
3. Choose the Computer and Software
The computer determines what your machine can run smoothly. A Raspberry Pi 4 or 5 is efficient, quiet, and suitable for many classic arcade systems. A mini PC or refurbished desktop is better for more demanding emulators, modern indie arcade games, and higher-resolution front ends.
Common software options include:
- RetroPie: Popular on Raspberry Pi, with a large community and broad controller support.
- Batocera: Easy to install, polished, and suitable for both Raspberry Pi and PC hardware.
- LaunchBox and Big Box: Strong front-end option for Windows-based machines.
- Recalbox: Simple interface and beginner-friendly configuration.
Important legal note: emulation software is generally legal, but downloading game ROMs you do not own may violate copyright law. Use legally purchased game collections, homebrew titles, public domain games, or backups you are legally permitted to create in your jurisdiction.
4. Build or Assemble the Cabinet
If you are cutting your own cabinet, start with the side panels because they define the final shape. Use one finished side as a template for the second side so the cabinet remains symmetrical. Then install the base, back, monitor supports, speaker panel, marquee area, and control panel.
Use wood glue and screws for strength, but drill pilot holes first to prevent splitting. MDF is affordable and smooth, but it is heavy and creates fine dust when cut. Plywood is lighter and more durable, though it may require more finishing work. Always wear eye protection and a dust mask when cutting or sanding.
Before painting, test fit the monitor, speakers, computer, and control panel. This prevents the common mistake of finishing the cabinet and then discovering that a cable, bracket, or monitor angle does not fit properly.
5. Install the Monitor, Audio, and Power
Mount the display securely using a VESA bracket or a wood support frame. The screen should sit at a comfortable viewing angle and should not shift when the cabinet is moved. If you use a TV, disable unnecessary image processing and set it to game mode if available.
For sound, small speakers mounted behind a drilled speaker panel are usually enough. Many builders use inexpensive powered PC speakers, remove the plastic casing, and mount the drivers inside the cabinet. Keep volume controls accessible, either through the coin door area, rear panel, or a small service opening.
Install a surge-protected power strip inside the cabinet and route all power cables neatly. If possible, use a single external power cord for the whole machine. This makes the cabinet easier and safer to operate.
6. Wire the Controls
Arcade controls are straightforward if you work methodically. Each button typically connects to the USB encoder with one signal wire and one ground wire. Many kits include daisy-chain ground wires, which simplify installation.
A standard two-player layout often includes:
- Two joysticks, one for each player.
- Six action buttons per player for broad game compatibility.
- Player one and player two start buttons.
- Coin or credit buttons, unless you install a working coin door.
- Optional admin buttons for pause, exit, menu, and save states.
Label the wires as you connect them. After wiring, connect the encoder to the computer and test every input before closing the control panel. Fixing a loose connector now takes seconds; fixing it after final assembly can take much longer.
7. Configure the Software
Install your chosen arcade operating system or front end, then configure display resolution, audio output, controller mapping, and game directories. Take time to create a clean menu structure. A serious build should feel like an appliance, not a desktop computer hidden in a box.
Recommended setup steps include:
- Update the system before adding games or artwork.
- Map controls carefully for both players.
- Set hotkeys for exiting games and opening menus.
- Add legally obtained games and confirm each one launches correctly.
- Back up the configuration once everything works.
If children or guests will use the machine, hide advanced settings and limit access to system menus. This reduces accidental configuration changes.
8. Budget: What You Should Expect to Spend
Costs vary widely, but the following budget ranges are realistic for a two-player build:
- Basic bartop build: $450 to $700, using a Raspberry Pi, modest monitor, and budget controls.
- Mid-range upright build: $800 to $1,200, using a better cabinet, 27-inch display, quality controls, and improved audio.
- Premium cabinet: $1,300 to $2,000, with custom artwork, high-end joysticks, coin door, LED buttons, and a mini PC.
Do not spend all your money on the computer. In day-to-day use, the controls, screen position, and cabinet stability affect the experience more than raw processing power.
9. Final Testing and Maintenance
Once assembled, run the machine for at least one hour with the back panel closed. Check for heat buildup, audio buzzing, screen flicker, loose buttons, and unstable controls. If the cabinet feels warm inside, add ventilation before regular use.
Maintenance is simple: keep dust out, avoid moisture, back up the software image, and periodically inspect wiring connections. A well-built home arcade cabinet can last for many years, especially if the control panel is accessible for repairs.
Conclusion
Building an arcade machine is a serious but achievable project when approached in stages. Start with a clear cabinet plan, buy compatible parts, use proven software, and test each system before final assembly. With a realistic budget and careful wiring, you can create a reliable arcade cabinet that looks professional, plays well, and becomes a lasting centerpiece in your home or studio.
