Compact 4U rackmount chassis

The iStarUSA D400-6SE-SL is a 4U rackmount server chassis designed for environments that need multiple front-accessible drives. It suits IT teams building storage-heavy nodes or media servers where optical and hot-swap bays are required.

Before ordering verify space and cooling

Confirm your rack depth can accept a 4U unit and that the single 80mm rear fan provides sufficient airflow for your component thermal load. Check that your motherboard mounting pattern aligns with the seven expansion slots and that the power supply form factor fits the internal layout.

Six 5.25-inch bays shape the build

The six external 5.25-inch bays dominate the front panel, letting you install optical drives, hot-swap cages or front I/O modules without using internal 3.5-inch slots. Two external and two internal 3.5-inch bays remain for additional hard drives, so the chassis favours front-access density over raw internal capacity.

Questions about this item

What comes with the D400-6SE-SL and what must I buy separately?

The chassis provides six external 5.25" bays, two external 3.5" bays, two internal 3.5" bays, seven expansion slots and one 80mm fan. You will need to supply the motherboard, power supply, drives and any additional cooling.

Which drive-bay layout suits a build that needs many removable drives?

Choose this model when you need six 5.25" bays for optical drives or hot-swap trays plus two external 3.5" bays for quick-access storage; the two internal 3.5" bays handle fixed drives.

What does the single 80mm fan mean for airflow in a 4U rack?

One 80mm fan delivers baseline front-to-rear airflow; high-density or high-wattage builds will likely require extra fans or a more powerful power-supply fan to keep temperatures stable.
