Redditor resells PC as local AI rig for nearly double the price

A Redditor couldn't sell an old AM4 system at €750, but after adding two R9700 GPUs and demoing Qwen3.6 and ComfyUI, it sold for €5,400; buying replacement cards cheaper left him effectively earning €1,300 for the original system. The post warns buyers to check used-parts prices before buying a local-AI PC.
