Blowtorch and PSU Cables Become Heavy Copper PC
A custom gaming rig built from a repurposed blowtorch and cut power supply cables weighs nearly 20 kg, prioritizing raw aesthetic over traditional design constraints.
A hobbyist has constructed a gaming computer that replaces standard plastic components with heavy copper piping and an old blowtorch. The build, shared on Reddit by a user known as Old-Mate-Fetus, features a reservoir made from a Primus blowtorch and custom cabling derived from a Corsair 850W power supply. The result is a dense, industrial-looking machine that weighs close to 20 kilograms.
According to GN technics/hardware (en-US), the project showcases a high level of manual fabrication skill. The creator intended to let the copper tarnish naturally over time, embracing the patina as part of the design. This approach contrasts with typical consumer electronics, which are designed to remain pristine and uniform in appearance.
Heavyweight Components Define Rig
The internal hardware includes an AMD Ryzen 7 9800X3D processor and a Gigabyte 9070 XT Gaming OC graphics card. To manage heat, the build utilizes specific cooling blocks from Alphacool and Heatkiller, along with Noctua Industrial fans. The system is housed in a custom wooden case, adding to the overall mass and structural rigidity of the setup.
The use of a DDC pump with a custom enclosure further illustrates the bespoke nature of the project. While the core computing components are standard retail products, the way they are integrated and cooled is entirely handcrafted. This method allows for unique aesthetic choices that are impossible with pre-built systems.
Repurposing Industrial Tools
The most distinctive feature is the reservoir, which is fashioned from an old blowtorch. This component, typically associated with heavy industry or mechanics, has been adapted to hold liquid coolant. Piping extends from the torch, connecting to the rest of the cooling loop. The creator described the look as artsy, noting the contrast between the functional hardware and the raw material.
Custom cables were also created by cutting and reworking wires from a Corsair power supply. This practice, while effective for custom loops, carries inherent risks regarding insulation and safety if not done correctly. The trade-off is a visual cohesion that matches the copper theme, eliminating the clutter of standard black or white wires.
Trade-offs of Custom Builds
This type of build requires significant time, skill, and cost to achieve. It is not a practical solution for most users due to the weight and the difficulty of maintenance. However, it demonstrates the limits of what can be done with standard PC components when combined with external materials.
The creator plans to use the machine for gaming, including titles like Overwatch. The decision to let the copper tarnish suggests a long-term perspective on the build's appearance. It is a statement piece that values craftsmanship and unique design over convenience or portability.
