I've put literally thousands of these into production servers across the USA (thus the indicated ownership level). I cannot recall a single one being DOA or one being replaced due to a failure (sheetrock dust and water damage aside). I purchased one for a home system serving media and running VMware Workstation for various tasks. The extra cost was absolutely worth it for the reliability and performance (802.3ad trunks at home??).
