Thank you for reaching out about optimizing the QNAP TVS-h874-i5 NAS for silent operation. Your approach of choosing the 8-bay case for better airflow and larger fans is a solid first step. Replacing the stock fans with quieter ones is indeed a viable solution, although it's essential to ensure compatibility with the NAS's specifications regarding pin count and connector type. As for the power supply unit (PSU), upgrading to a higher wattage PSU like the Seasonic SS-400H1U 400 Watt or the 350W option could potentially reduce noise while maintaining sufficient power delivery. However, confirming compatibility and connector specifications is crucial before making any modifications. Unfortunately, detailed specifications for these components are often not readily available from QNAP, so some research or consultation with technical experts may be necessary to ensure compatibility and effectiveness. With your budget and RAID configuration in mind, these modifications could significantly improve the overall acoustic performance of your NAS setup.
