DIY Builder Creates Dual RTX 3090 Inference Rig
A Reddit user showcased a homemade '2400cc Inference Racer': two used RTX 3090s linked via NVLink, driven by a bare 7840U ThinkPad motherboard, cooled by a VW Golf radiator and about 2.4 litres of coolant, with PCIe routed through WWAN and SSD slots and a patched BIOS. It runs Ubuntu and serves Qwen3.8-27B via vLLM.
