The console wars are dead. And what killed them wasn’t rising RAM prices, GPU scarcity, tariffs, or any sort of monopolistic practices. It was one modder who was tired of the multi-ecosystem approach. Chinese hardware enthusiast 小宁子 XNZ (or XNZ for short) looked at her collection of gaming consoles, realized she was constantly swapping cables and power supplies just to access different game libraries, and decided to do something about it. The result is the Ningtendo PXBOX 5, a custom-built system that combines PlayStation 5, Xbox Series X, and Nintendo Switch 2 hardware into a single triangular chassis that switches between all three platforms with a button press. One console to rule them all…
XNZ stripped each console down to its motherboard and mounted them on three sides of a custom aluminum cooling block, inspired by the old trash can Mac Pro design. A single 250-watt power supply feeds everything, while a Phanteks fan at the bottom pushes air through the shared heatsink. Press the button on top and an Arduino board handles the switching logic, cycling through the three systems in about three seconds. A front-mounted LED strip glows blue for PlayStation, green for Xbox, or red for Switch 2, so you always know what’s active. The catch is you need to close your game before switching to avoid overloading the power supply, but that’s a small price to pay for having Sony, Microsoft, and Nintendo living peacefully under one roof. Both the PS5 and Xbox are digital-only versions, so no disc drives made it into the final build.
Designer: 小宁子 XNZ
XNZ pulled inspiration from Apple’s 2013 trash can Mac Pro, which remains one of the most divisive desktop designs Apple ever shipped. That machine had a triangular prism cooling system sitting dead center, with each of its three sides pressed tight against a separate component board. A fan at the top pulled hot air straight up through the whole assembly in one clean thermal column. Apple bet wrong on dual-GPU workstation builds and killed the product line, but the core thermal design was actually brilliant. For this project, it turned out to be the perfect blueprint. Three consoles, three motherboards, three sides of a triangle. The geometry practically solved itself.
Building that triangular heatsink presented a different problem entirely. XNZ needed dense fins capable of dissipating heat from three different APUs, but CNC machining quotes came back at around $700. Metal 3D printing wasn’t much better, and both options involved waiting in manufacturing queues that would kill any chance of rapid iteration. So she went old school. Really old school. We’re talking 1,500 years old.
Lost-wax casting has been around since ancient China, traditionally used for intricate bronze artifacts like the Yunwen Bronze Vessel. The principle is simple: carve a detailed model in wax, coat it in clay, melt out the wax, and pour molten metal into the cavity left behind. XNZ modernized the process by replacing wax with PLA filament from her 3D printer. She designed the heatsink in CAD software, printed it with support structures and cooling channels built right in, then encased the whole thing in high-temperature gypsum. The gypsum can withstand 700 degrees Celsius while PLA starts melting at 100 degrees and burns completely by the time you hit 700. Stick it in an electric kiln, run it through four heating stages over 12 hours, and you’re left with a clean ceramic mold ready for aluminum.
The first casting attempt failed halfway through when the molten aluminum cooled too fast and solidified before filling the entire mold. The fins were also too dense, causing the thin gypsum walls between them to crack. XNZ adjusted the fin thickness, changed their orientation to shorten the flow path, and recalibrated both the mold temperature and the aluminum pour temperature. Second attempt came out perfect. The surface captured fine details from the 3D print, including the layer lines from the support structures on the bottom. After sawing off the pouring gate and polishing the contact surfaces, she had a functional aluminum heatsink that cost maybe 50 bucks in materials instead of several hundred in machining fees.
Copper plates bolt onto two sides of the aluminum block where the PS5 and Xbox motherboards make contact. The third side, reserved for the Switch 2, doesn’t get a copper plate because Nintendo’s handheld apparently doesn’t need active cooling when docked. Thermal paste replaces the PS5’s stock liquid metal since the copper and aluminum combo provides enough thermal mass. During testing, the whole system ran Elden Ring for 30 minutes without overheating warnings, topping out at 60 degrees Celsius measured across the heatsink surface. That’s impressive considering you’ve got three separate APUs sharing one cooling solution and one 12-centimeter fan doing all the work.
The Switch 2 integration required a custom dock since the handheld needed to remain removable. XNZ gutted Nintendo’s official dock, pulled out the USB-C daughterboard and relevant electronics, and stuffed everything into a 3D-printed housing that attaches to the cooler’s third face. She wanted a spring-loaded ejection mechanism like a toaster, but metal springs couldn’t provide enough force to overcome USB-C port friction. The solution came from Bambu Lab’s MakerWorld, where she found a parametric spring generator that lets you customize dimensions through simple value inputs. She printed the entire dock assembly using dual-extrude printing with PLA for the rigid case and PETG for the flexible spring components. The two materials bond during printing so the spring stays permanently embedded in the structure but remains fully functional right off the print bed.
Power management turned out simpler than expected. The PS5 pulls 225 watts under full gaming load but drops to 4 watts in standby. The Xbox Series X shows similar behavior. A gallium nitride 250-watt power supply handles both consoles running in parallel as long as you’re only actively gaming on one at a time. The Switch 2 gets its juice through a transformer and USB-C PD trigger that converts the main rail voltage. An Arduino board sits inside the case managing power distribution and HDMI switching, triggered by that single button on top. Press it once and the LED bar changes color while the Arduino routes both power and video output to the next console in the sequence. Takes three seconds to complete the switch, which is faster than most people can close their game and navigate back to the home screen anyway.
The whole thing weighs less than having three separate consoles on your shelf and uses one HDMI cable, one power cord, and zero mental energy deciding which box to turn on. Sure, you lose disc drive functionality since both the PlayStation and Xbox are digital editions. And yes, the 250-watt ceiling means no running multiple games simultaneously or the power supply trips. But XNZ built a working proof of concept that platform exclusivity is a solvable engineering problem, not some immutable law of physics. Sony, Microsoft, and Nintendo have spent decades convincing people their ecosystems need to stay separate. One person with a 3D printer, some molten aluminum, and a weekend said otherwise.
