2 GPU RTX 5090 LLM fine-tuning Rackmount Build

This rackmount system pairs 2x RTX 5090 32GB 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-10k planning tier, intended for dedicated equipment rooms or datacenter rows.
