Compact tower for mini-ITX storage builds

The iStarUSA S-35-3M1RD is a black aluminium-and-steel tower that accepts a mini-ITX motherboard and provides three hot-swap 3.5-inch drive bays plus one internal 2.5-inch bay. It targets users who need dense, accessible storage in a small footprint. A single expansion slot and two front USB 2.0 ports complete the basic I/O.

Before ordering, verify motherboard and power supply

Confirm the board is mini-ITX and that the chosen flex-form-factor power supply fits the chassis layout. Ensure the SATA or SAS backplane matches the 6.0 Gb/s drives you plan to use. The single expansion slot limits add-in cards to one device. No other drive form factors are supported in the hot-swap bays.

Thermals, noise and power in normal use

One 120 mm fan handles airflow through the front panel and drive cage. Noise level will depend on the fan model selected and the drive count installed. Power draw is determined by the motherboard, drives and any add-in card rather than the chassis itself. Adequate ventilation around the tower helps maintain stable temperatures.

Questions about this item

Does the chassis come with drive trays and a power supply, or must they be purchased separately?

The unit includes three 3.5" hot-swap bays with trays and a single 120mm fan. A Flex ATX power supply is not included and must be bought separately.

Should I choose the 3.5" hot-swap bays or the single internal 2.5" bay for my main storage?

The three 3.5" hot-swap bays support 6.0Gb/s SATA or SAS drives and are designed for primary, high-capacity storage. The lone 2.5" bay is best reserved for an OS or cache drive.

What does the 6.0Gb/s SATA/SAS rating mean for actual drive speed in this tower?

The backplane supports up to 6.0Gb/s SATA or SAS throughput, so compatible hard drives will run at their full native speed without a bottleneck from the chassis.
