Compact Mini-ITX Enclosure

The iStarUSA S-21 is a tower chassis built for Mini-ITX motherboards measuring 17cm by 17cm. Its aluminium front panel and steel structure create a clean, gap-free appearance suited to entertainment or industrial settings. The compact footprint fits limited desk or rack space while supporting a single power supply. Builders needing E-ATX or dual-PSU layouts should look elsewhere.

Two 2.5-Inch Drive Bays

Two internal 2.5-inch bays provide room for a pair of SSDs or laptop-class hard drives, enough for an operating system plus a modest data volume. Only one expansion slot is available, so a single add-in card such as a GPU or NIC can be installed. The single included fan mount handles basic airflow; high-heat configurations will require careful thermal planning.

Front USB and RoHS Compliance

Two front-facing USB ports give convenient access for peripherals or install media without reaching around the back. The chassis meets RoHS green-compliance standards, confirming restricted-substance limits in its materials. No rear I/O cut-outs beyond the standard Mini-ITX shield are described, so port selection depends entirely on the chosen motherboard.

商品問答

Will my existing Mini-ITX motherboard measuring 17cm by 17cm fit inside this chassis?

Yes, the S-21 is designed for full-range Mini-ITX boards at exactly 17cm x 17cm, so your current board will mount without modification.

How can I verify the single supported fan is spinning correctly once the system is assembled?

Power on the chassis and watch the fan through the vent; you should see steady rotation and hear low airflow noise indicating the cooling path is active.

Does the box include a power supply or must I purchase one separately for the single supported PSU slot?

No power supply is installed or included; you must buy a compatible unit separately for the one supported PSU bay.
