Nas Standoffs: ((exclusive))

| Thread Type | Common Use | NAS Example | |-------------|------------|--------------| | #6-32 UNC | Standard PC cases | Old Cooler Master NAS chassis | | M3 | Mini-ITX, some backplanes | Fractal Design Node 304 | | M4 | Rack rails, HDD cages | Supermicro chassis, SilverStone |

Removing standoffs stuck to a motherboard screw. Use a proper standoff driver or risk spinning the entire post. nas standoffs

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. | Thread Type | Common Use | NAS

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. This gives you leverage and prevents over-tightening

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.

Hand-tightening works for test-fitting. Brass standoffs have shallow knurling for finger grip.
