  • Chassis TypeMini-Tower
  • Five hot-swap bays for SAS and SATA drives

Compact NAS Chassis

The SilverStone CS351B is a mini-tower server chassis designed for network-attached storage builds. It accepts Micro-ATX, Mini-DTX and Mini-ITX motherboards alongside a standard ATX power supply. Five hot-swap drive trays at the front support 3.5" or 2.5" SAS-12G and SATA-6G drives with dual status LEDs. Each tray includes an anti-theft lock to secure sensitive data.

Builders Who Need More Internal Bays

This case suits home or small-office NAS appliances that prioritise front-access hot-swap bays and a compact 25.1-litre footprint. Builders requiring eight or more internal 3.5" drives, full-height expansion cards beyond 368 mm, or CPU coolers taller than 82 mm should consider a larger tower or rack-mount enclosure instead.

Five Front Hot-Swap Bays

The defining specification is the five external 3.5"/2.5" hot-swap bays wired for SAS-12G and SATA-6G with LED indicators and lockable trays. This bay count and interface mix determines whether the chassis matches the planned drive topology and redundancy scheme.
