Rackowl 4U Rackmount Server Case

The Rackowl 4U Rackmount Server Case is a robust and versatile chassis designed for professionals who demand high-density storage, extensive hardware compatibility, and reliable operation in rack environments. Whether you're building a network-attached storage (NAS), a virtualization host, or a high-performance computing cluster, this 4U case provides the space and flexibility needed to accommodate enterprise-grade components.

Unmatched Motherboard and PSU Compatibility

Supporting a wide range of motherboard form factors—including EEB, CEB, ATX, Micro-ATX, Mini-ITX, Flex-ATX, and E-ATX—this case ensures you can install almost any server or workstation board on the market. The flexible PSU mounting options accept standard ATX power supplies as well as CRPS (Common Redundant Power Supply) and 2U units, allowing you to choose between cost-effective consumer PSUs or enterprise-grade redundant power for maximum uptime.

Massive Storage Capacity

With 13 drive bays (10x 3.5" and 3x 5.25"), the Rackowl 4U is perfect for storage-heavy applications. The 3.5" bays can house traditional HDDs or SSDs, while the 5.25" bays can be used for optical drives, hot-swap cages, or additional storage adapters. This makes it an excellent choice for file servers, backup systems, or media archives where capacity is critical.

Efficient Cooling and Airflow

To keep your components cool under heavy loads, the case includes multiple fan mounts: two 120mm fans at the front, four 80mm fans in the middle, and two 80mm fans at the rear. This configuration ensures excellent airflow from front to back, effectively dissipating heat from CPUs, GPUs, and drives. The front panel is equipped with a dust filter to minimize dust ingress, and the front door lock adds security for your valuable hardware.

Expansion and GPU Support

The case provides 7 PCIe slots, allowing you to install multiple GPUs, network cards, or other expansion cards. It supports GPUs up to 330mm in length and CPU coolers up to 150mm in height, giving you ample room for high-performance components. Whether you're building a deep-learning workstation or a rendering farm, this case can handle it.

Build Quality and Use Cases

Constructed from durable steel, the Rackowl 4U is built to last in demanding environments. Its rack-mountable design (4U height) fits standard 19-inch server racks. Typical use cases include:

• Enterprise server rooms and data centers
• Home labs and homelab enthusiasts
• Video editing and 3D rendering workstations
• Network security appliances (firewalls, routers)
• High-capacity NAS or SAN systems

With its extensive compatibility, massive storage options, and robust cooling, the Rackowl 4U Rackmount Server Case is a smart investment for anyone needing a reliable and expandable server chassis.
