I have a SC523L that could benefit from better airflow management. While there are parts like the MCP-310-28012-0N, that is designed for a dual cpu system, whereas mine is single (and I also want to direct some cooling to NVMe SSDs and a few IO expansion cards). I was thinking about creating my own mylar air shroud, but I can't find similar stiffness material to start with. Does anyone have pointers on where I could get this material and what the best way to go about construction would be?
