The London-based studio Billet Labs, renowned for its innovative approach to PC cooling systems, has released a teaser for a truly unusual build. Enthusiasts have decided to abandon traditional cases and place gaming PC components inside (or more precisely, under) an authentic 50-kg Victorian-era cast iron radiator.
This project can be confidently classified as steampunk. The massive, sturdy radiator with wide rounded sections and ornate legs looks very impressive, and its utility is undeniable: during winter, such a system unit will not only entertain with games but also literally warm the room with heat from a powerful processor and graphics card.
The creators have unveiled the “insides” of the unfinished assembly. All major PC components are mounted in the lower part of the huge radiator. From the rear, you can discern the video card outputs, the motherboard’s input-output panel, and the power supply wall.
The project is currently at the stage of cooling system installation. The craftsmen have begun laying copper tubes and installing heat exchangers, which will connect the PC’s hot components with the massive case. “By the time I’m done with the tubing, this whole thing will be wrapped in copper… It’s going to be just insane,” said the creator of the assembly.
As of 2025, cooling technology has seen significant advances, with trends leaning towards more sustainable and silent options. Using a 50-kg cast iron radiator highlights both the creativity and technical challenges faced by Billet Labs. Typical air or liquid cooling systems may become obsolete in creative custom builds with such high thermal capacity, allowing even the most powerful systems to run absolutely noiselessly without overheating.
“Integrating tradition with technology is our homage to engineering ingenuity,” remarked an industry expert.
Billet Labs has yet to disclose the exact specifications of the computer components, but undertaking such a large-scale project for a typical office or multimedia setup would be pointless. The high heat capacity of 50 kilograms of cast iron and 10 liters of coolant will let even the most powerful system run completely silently and without overheating.
