The Silverstone SST-RM41-506 Rack ATX CEB micro ATX Mini-ITX is a compact 1U/2U-style rack server case designed to accommodate ATX, SSI-CEB, micro ATX and Mini-ITX motherboards. It accepts ATX (PS2) and redundant Mini-PS2 power supplies and provides flexible storage options including bays for 5.25", 3.5" and 2.5" drives as well as slim optical drives. The front panel integrates a handle for easy carriage and access, plus two USB 3.0 ports for convenient external device connections. With external dimensions of 430 mm (W) x 446 mm (D) x 176 mm (H), the chassis is intended for space-efficient server installations and supports front-to-back airflow aided by two pre-installed 80 mm PWM exhaust fans.
Advantages
The case combines compact rack compatibility with versatile internal layout choices, allowing installation of ATX and SSI-CEB motherboards while still maintaining a shallow depth suitable for many rack cabinets. Front-mounted USB 3.0 ports and an integrated handle improve accessibility for routine maintenance and quick peripheral connections. Pre-installed 80 mm PWM exhaust fans and a front-to-back airflow path reduce thermal buildup, and reserved mounting holes simplify fitting sliding rails for rack deployment.
Suitable for
- Small to medium rack servers requiring ATX or SSI-CEB motherboard form factors
- Network appliances, storage nodes or virtualization hosts with limited rack depth
- Environments needing front-access USB 3.0 and easy chassis removal for maintenance
- Systems that benefit from compact cooling with dual 80 mm exhaust fans

How to use
Install the chosen motherboard (ATX, SSI-CEB, micro ATX, or Mini-ITX) onto the supplied standoffs and fit the compatible power supply in the rear PS2 bay. Populate drive bays with 5.25", 3.5" or 2.5" storage devices or slim optical drives as required, observing the 200 mm maximum length for expansion cards. Connect front-panel USB 3.0 to the motherboard header for high-speed external connectivity. Ensure the two 80 mm PWM fans have unobstructed airflow from front to rear and route cables to maintain a clear airflow path.
Usage recommendations
For stable thermal performance, use the case in a rack with unobstructed front and rear ventilation, maintain moderate ambient temperatures, and periodically clean the 80 mm fan intakes. When installing sliding rails, verify alignment with the reserved mounting holes and select rails rated for the installed system weight. Choose SSDs or enterprise 2.5"/3.5" drives depending on performance and storage density needs, and confirm that any additional expansion cards do not exceed the 200 mm length limit.
