2400cc Inference Racer: Dual RTX 3090 motors, NVLink turbo, naked 7840U ThinkPad ECU, VW Golf radiator

The "2400cc Inference Racer" is a custom-built system featuring dual RTX 3090s, NVLink, and a naked 7840U ThinkPad. Housed in a chipboard chassis, it uses a €24 VW Golf radiator for cooling, holding around 2.4 litres of coolant, which inspired its "2400cc" designation. Despite its unique cooling setup, the creator notes its reliability is "excellent," with leaks of less than 100 ml/day, especially when not too warm, showcasing peak home inference engineering.

Unlike typical custom builds, this project uniquely integrates a €24 VW Golf radiator for cooling, demonstrating an unconventional approach to home inference system design.
