1 GPU RTX 4090 Local dev workstation Home Lab Build

This home lab system pairs 1x RTX 4090 24GB with Ryzen 9 9950X for daily model prototyping, CUDA testing, and containerized experiments without cloud lock-in. It uses serviceable air cooling with easy-access filters in a homelab-friendly tower chassis and is positioned in the under-5k planning tier, suited to owner-operated lab environments with direct physical access.
