Compact Storage Tower

The iStarUSA S-35-3DE1RD is a mini-ITX tower chassis built around three trayless 3.5-inch hot-swap bays. It targets users who need dense, accessible storage in a small footprint, such as home NAS builders or small-office file servers. A single internal 2.5-inch bay and one expansion slot complete the internal layout.

Aluminium Front Panel Build

A 4 mm aluminium front panel gives the black steel structure a rigid feel while exposing the red hot-swap handles for quick drive changes. Two front USB 2.0 ports provide convenient peripheral access without reaching around the back. The trayless design means 3.5-inch SATA or SAS drives slide directly into the bays, reducing part count and installation time.

Single 120 mm Fan Cooling

One 120 mm fan mounts in the chassis to move air across the drive bays and the mini-ITX board. In typical storage workloads the airflow keeps drive temperatures stable while the fan runs at modest speeds. The chassis supports Flex ATX power supplies, letting builders match power capacity to their specific component choices.

Questions about this item

What drive interface does the 3.5" hot-swap backplane support and what is its maximum speed?

The backplane accepts SATA and SAS drives and is rated for 6.0Gb/s operation.

What motherboard form factor and expansion slots fit inside the 8.90" x 8.68" x 12.76" chassis?

Only mini-ITX motherboards are supported, with a single expansion slot available.

How do you install a 3.5" drive in the trayless bays and what step is often missed?

Slide the drive straight into the bay until the connector seats, then press the red handle down to lock it; the handle must click fully closed or the drive will not be secured.
