Do not use the mystery bag that came with your $20 Chinese case. Invest $10–15 in a known brass kit from a brand like StarTech, SilverStone, or even a reputable Amazon seller (check reviews for “M4” mentions). Buy a proper 5.5mm hex driver – your fingers will thank you.
Rating: 4.7/5 Price Range: $5–$15 (for a mixed kit) Best For: DIY NAS builders, server rack mounts, PC enthusiasts First Impressions Let’s be honest: nobody gets excited about standoffs. They come in a small plastic bag, they look like tiny metal nuts, and most people only think about them when something doesn’t fit. But after building multiple NAS devices—from a humble 2-bay TrueNAS setup to a rackmount 12-bay Unraid server—I’ve learned that good standoffs separate a reliable server from a short-circuited disaster . nas standoffs

Worse: A missing standoff under a critical power plane can cause intermittent shorts. I’ve seen a 6-drive RAIDZ2 go poof because the builder used nylon standoffs everywhere, breaking the ground path. Rating: 4
One pro tip: Thread a spare screw into the standoff before installing it into the case. This gives you leverage and prevents over-tightening. A NAS runs 24/7. Vibration from hard drives can loosen cheap standoffs over months. Loose standoffs = floating motherboard = random crashes or USB dropouts.
Removing standoffs stuck to a motherboard screw. Use a proper standoff driver or risk spinning the entire post.
