Rosewill RSV-R4100U 4U Server Chassis
This 4U chassis offers seven internal 3.5″ HDD bays with room for two additional 5.25″ devices. It is ATX/CEB compatible, featuring seven PCI expansion slots for add-on cards. Cooling is addressed with a front 120mm PWM fan plus two rear 80mm PWM fans, designed to balance drive cooling with manageable noise. The chassis supports standard front-loading drive bays and is suitable for mid-range server or storage builds where expandability matters.
Rosewill RSV-R4000U 4U Server Chassis
With eight 3.5″ bays plus options for three 5.25″ drives, this model emphasizes high storage density in a 4U footprint. It includes four pre-installed fans for improved airflow and heat management. Its ATX/CEB compatibility provides broad motherboard support, making it a capable choice for storage-heavy deployments or general-purpose servers that require significant I/O capacity.
GPERHUAN 4U Server Cabinet Case
This modular 4U rack case focuses on security with a lockable front door and a dust-filter design at the intake. It supports 12 x ATX/M-ATX/Mini-ITX form factors in flexible internal architecture, including a 7-slot PCI expansion layout. The combination of security and expandability makes it a practical option for organized data centers and office server rooms where access control is important.

It supports EATX/ATX/MATX/Mini-ITX motherboards, with a front 2x120mm fan setup and rear 2x60mm fans for comprehensive airflow. The broad motherboard compatibility and multiple fan options suit mixed hardware builds that require scalability within a 4U enclosure.
Rosewill RSV-L4412U 4U Hot-Swap HDD Server Case
This 4U chassis emphasizes high drive density with 12 bays organized for easy expansion. It includes front 3x120mm fans and rear 2x80mm fans, providing robust cooling for dense storage configurations. The chassis is designed for E-ATX compatibility, offering substantial room for growth in enterprise-like environments while keeping a manageable depth at 25 inches.
Buying Guide: Key Purchase Considerations
- Drive capacity and configuration: Assess how many 3.5″ and 2.5″ bays you need, as well as any hot-swap requirements. Consider future expansion plans when choosing bays and backplane support.
- Motherboard and form factor compatibility: Ensure the chassis supports your intended motherboard size (ATX, MATX, Mini-ITX, or E-ATX) and check clearance for I/O shield and power supply placement.
- Cooling and noise: Look for front and rear fans, air intake paths, and potential support for radiator integration if you plan liquid cooling. PWM fans help with dynamic cooling while controlling noise.
- Security features: A lockable front door or chassis side panels protect hardware in shared spaces. Dust filters can extend component life in dusty environments.
- Physical dimensions: Verify depth, width, and rack compatibility. Ensure the unit fits your existing rack setup and leaves space for rear cable management.
- Expansion slots and PCI compatibility: Confirm the number of PCIe slots and compatibility with your cards, especially in 4U form factors where space is constrained.
- Serviceability and cable management: Favor designs that allow easy drive replacement and organized cabling to maintain airflow and reduce maintenance time.
- Material and build quality: Look for steel construction with reinforced mounting rails and sturdy chassis corners to withstand rack mounting and daily operations.
- Cost vs. value: Balance initial cost with long-term operational needs, including potential energy efficiency of cooling and the efficiency of space in your data center or office rack.
When evaluating options, create a short list of must-have features (e.g., number of drive bays, ease of maintenance, front-to-back airflow). Compare models by cooling efficiency, expansion options, and security features to determine which chassis best aligns with your deployment goals and ongoing operating costs.
