218-pound PC built inside a cast-iron Victorian radiator — cooling an RTX 5090 'probably out of the question'

Victorian radiator, oodles of copper pipe, pump, water blocks, trio of slim fans

Another nice touch with this fantastic PC build project was the choice of the power button. Felix sourced a sprung antique brass gear lever to power up the PC stylishly. This was fitted into one of the side vents on the rad using a custom mount.

Before the end of the video, we see the antique cast-iron PC used for a bit of gaming and benchmarking . In a ‘torture test,’ drawing about 520W of power for over an hour, the water temperature appeared to stabilize at under 30C. Notably, the RTX 5080 peaked at 75 °C during the most extreme testing Alex could throw at it.

Finding an antique cast-iron radiator isn't that easy in 2026, but at least Amazon still sells some modern ones in various sizes.
