Compact tower for four hot-swap drives

The iStarUSA S-35-DE4SL is a mini-ITX tower chassis built around four trayless 3.5-inch hot-swap bays. It targets home-lab builders and small-office users who need dense, accessible storage in a desktop footprint. A single internal 2.5-inch bay and one expansion slot complete the platform.

Sustained airflow across dense drive stack

One 120mm fan pulls air through the front panel across all four drive bays, keeping temperatures stable during continuous read-write workloads such as backups or media serving. The aluminium front panel and steel frame resist flex when drives are swapped under load.

Thermals noise and power in daily use

The single fan runs at modest speed, so acoustic output stays low in typical office or living-room settings. Power draw is limited to the installed mini-ITX board and up to four SATA or SAS drives, with no additional chassis overhead. Front USB 2.0 ports provide convenient peripheral access.

Questions about this item

How loud and warm does the chassis get when the single 120 mm fan runs continuously?

The chassis includes one 120 mm fan that provides active airflow through the four hot-swap bays; noise and temperature will depend on the drive load and ambient conditions.

Which power supply and motherboard must I already have to install this tower?

You need a mini-ITX motherboard and a Flex ATX power supply; the chassis has one expansion slot for a low-profile add-in card.

Can I keep using my older 3.5" SATA drives in the four trayless bays?

Yes, the bays support 6.0 Gb/s SATA and SAS hard drives, so existing 3.5" SATA drives will work without adapters.
