Billet Labs’ WALL-Y makes a high-end PC look like an industrial control panel: it hangs on a metal backplate, with polished copper and brass plumbing, analog gauges, and exposed mechanical details. It is a working custom computer as well as a steampunk-style art object—but its striking copperwork is not proof that it cools better than a conventional liquid-cooled PC.
What is WALL-Y?
WALL-Y is a wall-mounted custom PC build by Billet Labs. Instead of hiding its components in a conventional tower, it puts the hardware and cooling loop on display. The result sits somewhere between a workstation, a liquid-cooling project, and an industrial-art installation. It is a one-off custom mod, not a consumer PC case or turnkey product. ThinkComputers identifies the build as Wall-Y; Hackaday’s coverage documents its design and construction details.

Reported hardware
The available component list points to a capable system, but not every specification is settled. In particular, coverage disagrees about the graphics card.
| Part | Reported specification | What to know |
|---|---|---|
| Processor | AMD Ryzen 9 9950X | Listed by ThinkComputers. |
| Graphics card | Nvidia GeForce RTX 3090 or RTX 3090 Ti | Reports conflict; the exact model should not be treated as confirmed. |
| Motherboard | ASUS Mini-ITX | The exact model is not established in the available component list. |
| Memory | 64GB Corsair | Reported by ThinkComputers. |
| Storage | Kingston M.2 SSDs | An 8TB total capacity is claimed by another report, but should be attributed rather than treated as independently verified. |
| Power supply and cables | Phanteks Revolt PSU; CableMod cables | Reported by ThinkComputers. |
| Cooling and mounting | Custom liquid loop with copper hardware and exposed copper/brass plumbing; wall-mounted metal panel | Visible design details are described in Hackaday’s coverage; exact pump, radiator, coolant, and loop specifications are not established. |
These specifications come from ThinkComputers’ component list and other coverage. The discrepancy between RTX 3090 and RTX 3090 Ti is also reflected in Yanko Design’s report. Without a definitive primary build specification, it is better to leave the GPU model unresolved.
How the copper loop fits into the design
Copper is a familiar heat-transfer material in PC cooling, including in cold plates that draw heat from processors. WALL-Y makes copper part of the visible architecture rather than concealing the cooling hardware inside a case. Its copper and brass plumbing traces the loop across the wall panel, turning a functional system into its most prominent visual feature.

The basic cooling job remains conventional: cold plates transfer heat from components into coolant; a pump moves that coolant through the loop; and a radiator with fans releases heat into the room. The exact routing and component models are not documented in the coverage, so a precise flow diagram would be guesswork.

Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Clear out junk files and repair common Windows errorsFree Scan →Scan for outdated or missing drivers - takes under a minuteDriver Scan →Exposed copper pipe is not, by itself, a radiator, and copper’s conductivity does not establish that WALL-Y runs cooler than another PC. Temperatures depend on the complete setup: cold-plate contact, pump, radiator area, airflow, fans, coolant, flow, and the hardware’s heat load. No controlled thermal comparison or independent benchmark data is available in the cited coverage.
The finish is part of the appeal, but polished copper can change with handling, oxidation, and exposure. Keeping it bright may take periodic cleaning or re-polishing. That maintenance is a design trade-off, not a cooling requirement.

What the gauges tell you—and what they do not
Hackaday describes analog instruments for coolant temperature, loop pressure, and the 12-volt rail, plus a temperature gauge mounted on the graphics card. That GPU-mounted gauge reportedly measures the card’s exterior temperature, not the GPU’s die or hotspot temperature. It should not be read as a standard GPU-core telemetry value.
A coolant-temperature reading tells you about the loop, not directly about the CPU package or GPU core. A pressure gauge can provide a visual indication of loop pressure, but it is not a substitute for monitoring temperatures, pump behavior, or component sensors. Analog dials suit WALL-Y’s control-panel appearance; software or motherboard telemetry is still needed for precise component readings.
Why it reads as steampunk
The effect comes from a coherent set of choices: polished copper and brass, visible fittings, analog dials, a shiny metal mounting plate, and exposed fans. Plates conceal parts of the graphics card and power supply without hiding the build’s mechanical character. Hackaday notes that little plastic or paint is visible and compares the customized fans to throttle bodies or carburetors. Mounted vertically, the whole system resembles an ornate machine-room panel more than a desktop tower.

The materials do two jobs here. Some copper belongs to the cooling system; all of it contributes to the visual language. The same is true of the gauges: they can indicate conditions, but their prominent role is also aesthetic.

For a workshop, studio, or enthusiast space, WALL-Y is a dramatic showcase. Its open layout makes components and plumbing easy to see, and the metal panel provides a distinctive mounting platform. But an open, wall-mounted custom loop asks more of its owner than a normal enclosed PC.
- Mounting: The wall and anchors must safely support the system’s weight. Structural mounting deserves proper planning, particularly for a heavy assembly.
- Leaks and contact: Exposed fittings and tubing can be bumped or contaminated, and a leak has fewer barriers between coolant and hardware. The loop needs suitable components and leak testing before the PC is powered.
- Dust and service: Open hardware is exposed to dust and accidental contact. Servicing, draining, transport, and upgrades may be less convenient than with a removable tower case.
- Noise: The build’s metal fans are visually distinctive, but Hackaday describes their sound as resembling a jet taking off. That is a reported impression, not a measured noise level; it is still a reminder that showcase hardware may prioritize appearance over quiet operation.
- Materials and upkeep: Custom loops need compatible metals and regular inspection. Mixed-metal loops require compatibility planning; the available coverage does not establish the exact materials throughout WALL-Y’s loop, so it cannot support a claim about corrosion in this particular build.
- Electrical and structural safety: High-performance hardware can draw substantial power. Exposed metal, cable routing, mains power, and wall attachment call for careful planning; use qualified help where structural work or mains wiring is involved.
For anyone inspired to make a similar build, the useful lesson is to design the cooling and mounting around real operating needs first, then make the plumbing visible. Radiator capacity and airflow determine heat rejection; a coolant gauge cannot replace CPU, GPU, hotspot, or other component monitoring. A display-oriented open-frame case can offer some of the visual effect with less fabrication, while a custom copper-and-brass installation demands careful fitting, finishing, maintenance, and planning.

What is confirmed, and what remains uncertain
The build is consistently described as a Billet Labs wall-mounted PC with copper cooling hardware, exposed copper and brass plumbing, analog gauges, and an industrial presentation. The detailed component list reports a Ryzen 9 9950X, ASUS Mini-ITX board, 64GB of Corsair memory, Kingston M.2 storage, and a Phanteks Revolt PSU. But coverage does not agree on whether the GPU is an RTX 3090 or RTX 3090 Ti, and the exact storage capacity and several loop details are not firmly established.
Most importantly, the available reports show how WALL-Y is built and presented; they do not demonstrate that it outperforms a conventional liquid-cooled system. Its achievement is the union of functioning hardware and visible fabrication, not a documented benchmark win.
Verdict
WALL-Y is best understood as functional industrial art: a high-end custom PC arranged to make its cooling hardware, metalwork, and instrumentation part of the display. Its copper and brass give it a memorable steampunk identity, while the open wall-mounted form brings real compromises in noise, dust protection, maintenance, and installation. It is inspiring as a fabrication project, but not a practical blueprint for someone whose first priorities are quiet operation and low upkeep.
