One Console To Rule Them All: Inside the Triple-System Mod

A Chinese hardware modder has built what many players have only imagined: a single machine that houses the internals of a PlayStation 5, an Xbox Series X, and a Nintendo Switch 2, all living together inside a custom cylindrical tower. The community-nicknamed device, often referred to as the “Ningtendo PXBOX 5,” is not a commercial product but a one-off engineering experiment that shows how far enthusiast makers can push modern console hardware.

This article explores how the build works, what makes it technically possible, and why it matters for the ongoing debates around platform exclusives and the so-called console war. While inspired by the original reporting and the creator’s video, the analysis and structure here are entirely fresh, focusing on the engineering and broader implications of such a hybrid system.

From Daydream to Triple-Console Reality

Owning more than one console is now common: PlayStation and Xbox platforms share many third-party titles, while Nintendo’s systems offer their own library of exclusives and a hybrid handheld design. That abundance comes with drawbacks: three power bricks, three nests of cables, and constant HDMI juggling behind the TV.

The creator behind this build, known online as 小宁子 (XNZ), set out to solve that physical clutter problem rather than the software one. Her idea was not to hack operating systems together, but to:

• Place three official console motherboards inside one chassis
• Share a common cooling and power system between them
• Use a single button to switch between platforms in seconds

In doing so, she ended up constructing a tower that resembles a modern desktop or the 2013 cylindrical Mac Pro, with a central cooling core and three hardware blades wrapping around it.

Disassembling the Big Three: What’s Really Inside

Once consumer devices are stripped of their plastic shells, they often look more alike than different. That’s true of modern consoles too. Sony, Microsoft, and Nintendo all rely on a combination of system-on-chip (SoC), memory, storage, power, and thermal components laid out on a mainboard.

In this project, each console was carefully taken apart down to its mainboard. Official teardowns and repair guides have shown that:

• The PS5 uses a custom AMD SoC with high bandwidth memory interfaces and a large mainboard footprint, paired with a substantial heatsink and fan assembly.
• The Xbox Series X also centers around a custom AMD SoC, vertically oriented in the retail design with a large vapor chamber and a single top fan that pulls air through the chassis.¹
• The Nintendo Switch family, including its successor, uses a more compact board with a mobile-focused SoC and much smaller cooling hardware by comparison.

When viewed side by side without their stock casing and cooling, the PS5 and Xbox Series X motherboards occupy less volume than their towering shells suggest. Much of that bulk normally goes to heat dissipation and airflow, not silicon. That observation is what makes a shared, central cooling design feasible in a custom enclosure.

A Cylindrical Tower With a Shared Cooling Core

The heart of the triple-console machine is a cylindrical body with a central thermal core. Instead of each console keeping its original heatsink, XNZ designed an internal layout where all three boards face inward toward a shared cooling system. While the exact machining and 3D-printed parts are unique to her workshop, the underlying ideas can be broken down.

Why a Cylinder Makes Sense

The decision to build a tower reminiscent of the 2013 Mac Pro is more than an aesthetic choice. Cylindrical or radial layouts are common in compact performance PCs and some workstations because they provide:

• Even airflow distribution: A central fan can draw air in from the bottom and exhaust it through the top, or vice versa.
• Symmetrical motherboard placement: Each board can be attached to a different side of an internal frame, improving cable routing and spacing.
• Shorter airflow paths: Heat doesn’t have to travel through multiple chambers or around corners.

Apple formalized a similar approach in its 2013 Mac Pro, which used a triangular logic board structure and single fan for multiple components.² XNZ’s design applies that conceptual geometry to console mainboards instead of workstation GPUs and CPUs.

How the Shared Cooler Operates

The custom tower uses one large fan and a central heatsink assembly to cool whichever console is powered on. The engineering logic rests on a few points:

• Only one system runs at a time, so thermal output is limited to a single console’s TDP rather than the sum of all three.
• Heatpipes or direct-contact surfaces can route heat from each chip area into a common heatsink column.
• High static pressure fan design allows air to be pulled through densely packed fins, a technique widely used in server and workstation cooling.

Modern consoles already rely on large, efficient cooling designs. Sony’s official PS5 teardown, for example, reveals a sizable heatsink with heatpipes and a 120 mm fan optimized for quiet operation.³ By replacing these proprietary assemblies with a unified cooling spine, the mod trades OEM refinement for custom flexibility.

Powering Three Consoles With One Supply

At the base of the build sits a single 250 W PC-style power supply. At first glance, that seems surprisingly small, given that the PS5 and Xbox Series X both have nameplate power demands higher than 200 W under maximum load. However, two details make the arrangement viable in practice:

1. Again, only one console can be on at any moment.
2. The modder is using a custom, efficient power delivery scheme rather than running all three simultaneously.

In real-world testing, contemporary consoles rarely sustain their absolute peak draw. For instance, independent measurements have found the PS5 and Xbox Series X generally draw under 225 W during intensive gaming, often less in typical use, while also employing aggressive power management.⁴ A 250 W unit, particularly one designed for desktop systems, can therefore be enough if paired with careful wiring and noise/heat constraints.

The system relies on robust switching and clear physical separation: if two consoles were accidentally powered at once, the supply could be overloaded. That’s why this remains a modding showcase and not a ready-made consumer product.

Dockable Switch 2: Hybrid Within a Hybrid

One of the more imaginative aspects of the design is how it treats Nintendo’s hardware. While the PS5 and Xbox Series X motherboards are permanently mounted inside the cylinder, the Switch 2 board is integrated in a way that preserves its hybrid identity.

The modder designed a custom dock mechanism so that the Switch 2 motherboard can slot into the tower to share cooling and power, but also be undocked if needed. This maintains the handheld nature of the system, while still letting it become part of the unified living room stack. To accomplish this, several challenges had to be addressed:

• Alignment: Ensuring consistent contact with power and data pins when docked.
• Thermal interface: Making sure the Switch 2 SoC mates correctly with the tower’s cooling plate.
• Structural strength: Allowing repeated docking and undocking without damaging the board.

Although the specifics of the mechanism are unique to this build, the concept echoes the official Nintendo Switch dock, which connects the console to TV output and power via a compact interface. Here, that idea is extended into a fully custom mechanical and thermal system.

Instant Platform Hopping: The Single-Button Switch

On top of the tower sits a physical button. Pressing it cycles between PS5, Xbox Series X, and Switch 2 modes, with a delay of roughly three seconds as the hardware powers down one platform and brings up another. That experience is arguably the most magical aspect of the project: no HDMI swapping, no extra power buttons, just a single control that rotates you through three ecosystems.

Behind that simple UX lie layers of logic:

• Sequenced power control to avoid powering two motherboards at once
• Relays or solid-state switches that route the power supply’s rails to the active console
• Video switching from three HDMI outputs to one cable feeding the TV or monitor

HDMI switchers and multi-input receivers are common home-theater accessories. Integrating that function directly into the chassis transforms what would otherwise be a messy bundle of external gear into a clean, self-contained solution.

Does This End the Console War?

The creator playfully frames the device as a call to “end the console war” by literally placing rival systems inside the same box. In reality, it does something slightly different and more grounded: it reduces the physical friction of living in a multi-platform world while leaving platform exclusivity and digital ecosystems intact.

Even with all three motherboards inside the same tower, you still have:

• Separate accounts for PlayStation Network, Xbox Live, and Nintendo accounts
• Individual digital libraries and subscription services
• Unique controllers, accessories, and UI paradigms

What the device really challenges is the assumption that competing consoles must always exist as distinct hulking boxes under the TV. It gestures towards a future where form factor is decoupled from ecosystem. That idea isn’t entirely theoretical: Microsoft, Sony, and Nintendo all increasingly emphasize cloud services, backward compatibility, and cross-platform features, blurring sharp lines between generations and hardware revisions.⁵

Risks, Limitations, and Why This Won’t Ship as a Product

As ingenious as the mod is, it comes with major caveats that explain why no major manufacturer offers a similar device.

Technical and Safety Concerns

• Warranty and repair: All three consoles have been completely disassembled, voiding warranties and complicating future repairs.
• Safety compliance: Consumer electronics must pass strict electrical and thermal safety tests. A one-off custom build doesn’t undergo that level of certification.
• Thermal edge cases: While the cooling works in the modder’s tests, complex workloads, high ambient temperatures, or dust buildup could still cause overheating over time.
• Long-term reliability: Console designs are tuned for specific airflow and vibration patterns. Replacing them with a unified system might expose unforeseen failure modes.

Business and Licensing Barriers

• Platform control: Sony, Microsoft, and Nintendo all tightly control how their hardware is presented and used. A shared chassis would raise licensing and brand questions.
• Support costs: If a unified triple-console product existed, whose customer support line would you call when something fails?
• Limited demand: Most players are satisfied with one or two consoles and a TV with multiple HDMI ports. A three-in-one premium device would appeal to a small niche.

For these reasons, the mod is best understood as a commentary on hardware design and user experience rather than a blueprint for an upcoming retail device.

What This Build Says About the Future of Gaming Hardware

Even if the “Ningtendo PXBOX 5” remains unique, it raises useful questions about how future gaming hardware might evolve.

Convergence of Form Factors

We’re already seeing hardware convergence in several ways:

• PC-like internals: Both PS5 and Xbox Series X use familiar CPU/GPU architectures and SSD storage, much closer to modern PCs than earlier console generations.¹
• Hybrid concepts: Nintendo’s Switch line proved that handheld/TV hybrid devices can reach mass-market success, inspiring PC handhelds and cloud-first form factors.
• Cloud integration: Services like Xbox Cloud Gaming and remote play blur the line between local and remote execution, letting a single device tap into multiple ecosystems over time.

A future living room might rely less on multiple physical consoles and more on a combination of powerful local hardware, streaming boxes, and shared controllers. This mod exaggerates that idea by brute force: instead of virtual convergence, it offers literal convergence inside a shared shell.

Modding Culture as R&D

Projects like this serve as informal research-and-development experiments carried out in public by enthusiasts. Modders have historically influenced mainstream products—consider how early PC case modding popularized tempered glass side panels and RGB lighting, now common features in retail systems.

Similarly, creative approaches to docking, unified power bricks, or modular console designs might inspire aspects of future commercial hardware, even if the industry never sells a triple-console tower.

Frequently Asked Questions

Can three consoles really run from one 250 W power supply?

Not at the same time. The system is designed so only one console is active at any moment. Under that constraint, and with careful power routing, a 250 W unit can theoretically support each platform individually, assuming realistic gaming loads and efficient conversion. It would not be suitable for running all three simultaneously.

Does the mod change the software or operating systems?

No. Each motherboard still runs its original operating system and firmware. The mod is about physical integration—shared cooling, power, and video output—rather than hacking or combining the software environments of PlayStation, Xbox, or Nintendo.

Is this legal to build at home?

Modding personal hardware is generally legal in many regions as long as you’re not circumventing protections for piracy or distributing infringing copies of software. However, regional laws vary, and modifying hardware voids warranties and may affect your ability to obtain official support. This project is a personal build, not a commercial product.

Could a company ever sell a three-in-one console like this?

It’s highly unlikely. Platform holders have little incentive to share a chassis, and such a device would face serious licensing, support, and branding hurdles. On top of that, the market for an ultra-premium, niche product would be limited. Instead, the industry is more likely to continue exploring software and cloud-based ways of reducing platform friction.

Does this solve the console war?

It solves part of the hardware clutter problem, but it doesn’t merge ecosystems. Exclusive games, subscription services, and digital storefronts remain tied to their respective platforms. The build is better understood as a playful, symbolic gesture toward unity than a practical fix for platform fragmentation.
