A giant PC you can walk inside: eighteen thousand GB of RAM

Published on May 05, 2026 | Translated from Spanish

Forget compact towers. A team of enthusiasts has built a functional PC of colossal size, large enough for a person to walk inside. It's not a mockup; it's a real system with 18,000 GB of RAM and 12,000 watts of cooling that maintains 25 degrees internal temperature. The power consumption is monstrous, and the electricity bill can exceed one hundred euros per month.

A beast of silicon and liquid cooling 🖥️

The design allows physical access to every component. The motherboard, on a giant scale, houses RAM modules the size of a brick. The cooling system, with 12,000 watts of power, uses large-caliber water circuits to dissipate the heat generated by the hardware. Maintaining the temperature at 25 degrees Celsius is an engineering achievement, but the energy cost is so high it could rival the consumption of a small home.

The wet dream of a tinkerer with hoses 🔧

Imagine walking through your PC and having to dodge a heatsink the size of a microwave. If you have a breakdown, forget a screwdriver; you'll need a ladder and a work suit. Of course, you can say your tower has a hallway, and that to change the thermal paste you need to make an appointment. The electricity bill will arrive in an A3-sized envelope, but at least you can heat the house without radiators.
