3U Rackmount Chassis for Micro ATX/ATX Builds

The iStarUSA D-300SE is a 3U rackmount server chassis finished in black with a blue aluminium front bezel. It accepts Micro ATX and ATX motherboards and provides seven expansion slots for add-in cards. A single 60mm fan is included for airflow. The unit is new and constructed from aluminium and steel.

Suited for Compact Rack Deployments

This chassis suits builders who need four external 5.25" bays for optical drives or hot-swap cages, plus two external 3.5" bays and one internal 3.5" bay. It is not for systems requiring multiple high-wattage GPUs or extensive internal storage arrays beyond the listed bays. Buyers needing front-panel USB 3.0 or larger fan mounts should consider other form factors.

Verify Rack Depth and Motherboard Clearance Before

Confirm that your rack can accommodate the 20.80" depth and 19.00" width of the chassis. Ensure the chosen Micro ATX or ATX board fits within the 3U height restriction and aligns with the seven-slot backplane. Check whether the optional TC-ISF08 sensor board is needed for temperature and fan monitoring.

Questions about this item

What motherboard form factors does the D-300SE support?

The chassis accepts Micro ATX and ATX motherboards, so you must already own one of those form factors to install it.

Can I keep using my existing 5.25-inch optical drives and 3.5-inch hard drives with this case?

Yes, the front provides four 5.25-inch bays and two external 3.5-inch bays, plus one internal 3.5-inch bay for retained drives.

How do I confirm the system is running normally after assembly?

The front panel shows Power, HDD activity, Temperature and Fan status LEDs; the last two require the optional TC-ISF08 sensor board to function.
