2 GPU RTX 6000 Ada LLM fine-tuning Rackmount Build

This rackmount system pairs 2x RTX 6000 Ada 48GB with Xeon w7-2495X for repeatable LoRA and QLoRA runs with enough memory bandwidth for long-context datasets. It uses front-to-back high-static-pressure airflow in a 4U rackmount enclosure and is positioned in the under-20k planning tier, intended for dedicated equipment rooms or datacenter rows.
