iStarUSA D Storm D-400S3SE System Cabinet

The iStarUSA D Storm D-400S3SE System Cabinet is an ultra-compact, industrial-grade rackmount chassis designed to deliver big performance in tight spaces. With a practical 13.7-inch depth, this chassis maximizes rack density while providing a robust platform for demanding workloads. It is engineered to accommodate full-size ATX motherboards and a generous expansion suite, making it an ideal choice for compact servers, network appliances, industrial controllers, and compact workstations. Built for reliability in space-constrained environments, the D Storm D-400S3SE blends thoughtful cooling, accessible drive options, and flexible card space to support a wide range of applications without sacrificing performance or stability.

• Compact form factor with full ATX support: Despite its slim 13.7" depth, the D Storm D-400S3SE accommodates standard ATX motherboards, ensuring you can deploy familiar, cost-effective hardware. This combination of compact footprint and full-board compatibility is ideal for data centers, edge computing, and industrial deployments where space is at a premium, yet you don’t want to compromise on motherboard options or expandability.
• Extensive expansion capability: The system cabinet supports up to seven full-height add-on cards, giving you the breadth to scale your setup with PCIe adapters, RAID controllers, network cards, GPU accelerators, and other expansion modules. This makes the D- Storm D-400S3SE a versatile backbone for multi-purpose servers and compact workstations that require rich I/O and high performance in a compact chassis.
• Flexible storage configuration: Two external 3.5" drive bays provide ready-made storage solutions, while compatibility with the iStarUSA BPU-2535V2 backplane enables you to support up to four 2.5" hard drives. A dedicated 5.25" bay adds to the versatility, allowing the installation of optical drives or other front-facing peripherals. This storage mix is ideal for applications requiring a combination of fast SSD/SSD-like media and bulk HDD storage in a compact enclosure.
• Industrial-grade build for reliability: The D Storm line is designed to endure the rigors of industrial and enterprise environments. The chassis delivers sturdy construction, dependable power distribution compatibility, and a design focused on stable operation under continuous load. This makes it well-suited for 24/7 missions where consistent uptime and predictable performance matter most.
• Easy integration and rack compatibility: Built with standard rack infrastructure in mind, the D Storm D-400S3SE aligns with traditional data-center racks and provides straightforward installation, maintenance, and serviceability. Its compact profile reduces the footprint without sacrificing accessibility to front I/O, storage bays, or expansion slots, streamlining deployment in existing rack ecosystems.

How to Install iStarUSA D Storm D-400S3SE System Cabinet

• Step 1 – Prepare the rack and workspace: Ensure your rack is level and secure. Gather power, data cables, and any backplane or drive assemblies you plan to install. Verify that you have the appropriate ATX motherboard, expansion cards, and storage devices ready.
• Step 2 – Install the motherboard: Mount the ATX motherboard into the chassis using the provided standoffs and screws. Align I/O backplane cutouts and route the main power cables toward the back of the chassis while keeping cables tidy to promote airflow.
• Step 3 – Add expansion cards: Slide in your full-height add-on cards into the available PCIe/PCI slots. Secure each card with screws to prevent movement and ensure proper engagement with the backplane or motherboard.
• Step 4 – Configure storage: Install the backplane or drive cages for the two external 3.5" bays and, if using the BPU-2535V2, connect it to the appropriate backplane or controller. Place up to four 2.5" drives in the interior drive array as supported by the backplane configuration, and ensure data and power cables are neatly organized.
• Step 5 – Connect power and verify: Attach the power supply or backplane power connectors. Double-check all cable connections, reseat components if needed, and perform a post-assembly check before powering on to verify that fans, drives, and expansion cards initialize correctly.
