The iStarUSA D-400S3 Rackmount Enclosure is an ultra-compact, industrial-grade 19-inch chassis designed to deliver exceptional expandability without sacrificing footprint. With a thoughtful balance of depth, airflow, and accessibility, this enclosure is tailor-made for space-constrained data centers, labs, edge deployments, and rugged industrial environments. Its compact 13.7" depth enables tight rack installations while still providing robust support for mainstream components, making it an ideal foundation for compact workstations, compact servers, or modular compute nodes that demand reliable performance in a durable, space-saving chassis. Built to accommodate a wide range of hardware, the D-400S3 emphasizes versatility—giving administrators and integrators a single, scalable enclosure that can grow with evolving workloads and storage needs.

  • Compact 13.7" depth: Designed to fit comfortably in standard 19" racks, the D-400S3 maximizes usable rack space, reduces cable clutter, and simplifies cooling management in crowded environments.
  • Full-size ATX motherboard compatibility: The full-size I/O area supports all ATX motherboards, enabling broad platform choice and compatibility with mainstream CPUs, GPUs, NICs, and other essential components.
  • Expansion capacity up to seven full-height add-on cards: This chassis is built for dense expansion, allowing GPUs, RAID controllers, network adapters, and other PCI/PCIe cards to be installed in a compact footprint to handle demanding workloads.
  • Dual external 3.5" drive bays with support for up to 4 x 2.5" drives via BPU-2535: Perfect for flexible storage configurations, hot-swap options, and high-throughput data access in a compact server or workstation.
  • One slim 5.25" bay for optical or other slim devices: Provides additional versatility for media, diagnostic tools, or legacy peripherals without compromising overall rack efficiency.

  • Drive bays: Two external 3.5" drive bays; supports BPU-2535 for up to four 2.5" drives (adds flexible, high-density storage capacity)
  • Bay configuration: One 5.25" slim bay for optical or other slim devices
  • Chassis design: Industrial-grade rackmount enclosure built to endure demanding environments while delivering reliable performance

How to Install iStarUSA D-400S3 Rackmount Enclosure

  • Prepare the rack: Verify that the rack rails are compatible with a 19" rackmount chassis and install the rails according to your rack manufacturer’s guidelines. Ensure the mounting surface is clean and free of obstructions to promote proper airflow.
  • Mount the enclosure: Slide the D-400S3 into the rack, align mounting holes with the rails, and secure the chassis using screws or hardware provided by the rack kit. Confirm that the enclosure sits level and that there is sufficient clearance for rear cable management.
  • Install the ATX motherboard: Open the chassis access panel and mount your full-size ATX motherboard to the internal tray, aligning the I/O shield with the rear cutouts. Secure the motherboard with standoff screws and connect essential power and data cables, including the 24-pin ATX power connector and CPU power leads.
  • Configure expansion cards: Determine your workload and install up to seven full-height expansion cards into PCIe/PCI slots. Maintain proper spacing between cards to promote adequate airflow and reduce thermal throttling. Re-seat cards if any slot is initially difficult to engage.
  • Set up storage: Install drives into the two external 3.5" drive bays, or use iStarUSA BPU-2535 adapters to support up to four 2.5" drives, depending on your storage strategy. Route cables cleanly to the rear and secure drive trays to minimize vibration and movement during operation.
  • Install the slim bay device: If you plan to use a 5.25" slim device (optical drive or similar), insert it into the slim bay and connect its data and power cables. Ensure the cables are neatly managed to avoid obstructing fans or airflow pathways.
  • Power up and test: Connect the power supply, perform a POST check, and verify that all installed components are recognized by the system. Confirm that fans operate correctly and monitor thermals during a brief burn-in to ensure stable operation.
  • Cable management and airflow: Organize front-to-rear cables to improve airflow and reduce dust collection. Use any available cable routing channels or ties to maintain a clean interior, which helps maintain component longevity and consistent performance.

Highly recommend
Size: King
These pillows are super comfortable and feel just like hotel quality. They’re soft but still give great support for my neck and head. I’ve been sleeping much better since I got them. They stay fluffy and don’t go flat, and the material feels nice and cool. Definitely a great purchase

Time will tell
Size: King
I won’t actually use these for a few days when my mattress arrives. Unboxed this morning and they are not as plump and full as I expected but they’re laying out to expand. Overall first impression is they felt comfortable and I could adjust them with my hands. They seem well made and durable. Cant say anything yet about firmness or shape retention since I’ve not used them. They feel like they will be soft. So time will tell but so far I’m loving what I see.

HOTEL pillows King Quality is Great
Size: King
Just got these pillows today. I have never spent dollars on pillows; but I wanted Hotel Grand like the ones that I sleep on in the Hotels and these fit the bill. Large King is what I got and so far so good. Firm and Squishy like I like. I was impressed with the quality -- now lets just give them a few days rest. I am sure they will be GRAND.

Hotel Grand Pillows
Size: King
Very soft, comfortable and fluffy. I’m a side sleeper and don’t feel they go flat. I bought 2 king size pillows. I was initially looking for fluffy feather pillows… but this is the next best thing. I was pleasantly surprised. Turned out to be more comfortable than I thought they would be.
