Silverstone RM41-H08 4U server chassis 5×3.5 hot-swap 3×5.25 USB 3.1 Gen 1

4U rackmount chassis with five hot-swap bays

The Silverstone RM41-H08 is a 4U rackmount server chassis built for environments that need dense 3.5-inch storage with tool-less drive changes. It accepts SSI-CEB motherboards and provides seven standard PCI or PCIe expansion slots for add-in cards. Front-panel USB 3.1 Gen 1 ports give 5 Gbps connectivity for peripherals or maintenance media. Two pre-installed 80 mm PWM exhaust fans establish front-to-back airflow.

Compatibility checks before ordering

Verify that your rack depth can accommodate a 4U form factor and that the motherboard you plan to use matches the SSI-CEB mounting pattern. Confirm the power supply you intend to install fits the chassis ATX cut-out and provides the connectors your board requires. Ensure any expansion cards fit within the seven-slot limit and do not exceed the available length clearance. Check that the sliding rails you select match the pre-drilled mounting holes on the chassis sides.

Upgrade path from fixed-bay or tower servers

This chassis replaces tower or fixed-bay servers where drive swaps require downtime or tools. The tray-free, screw-less carriers with anti-theft locks let you exchange SAS or SATA drives while the system runs. The three 5.25-inch bays add room for optical drives or front-access accessories that smaller rack cases omit. The jump is worth it when you need five hot-swap 3.5-inch bays, SSI-CEB support and seven full-height slots in a single 4U envelope.
