SilverStone CS340 chassis offers four 3-mode hot-swap drive bays for compact NAS builds

SilverStone introduced the CS340 chassis to address the growing demand for compact network-attached storage solutions. This release matters because it offers a specialized form factor that balances high drive capacity with a small physical footprint. Users looking to build a dense storage server without sacrificing case size now have a dedicated option.

The CS340 is built around Mini-ITX and Deep Mini-ITX motherboard standards. It measures 220mm wide, 225mm high, and 300mm deep. The design includes a removable motherboard tray to simplify component installation and maintenance.
