Spacious 4U Rackmount Chassis

The Rosewill RSV-R4100U is a 4U steel server chassis built for rackmount deployment. It accommodates ATX, E-ATX, Micro-ATX, Mini-ITX and SSI CEB motherboards. Seven internal 3.5-inch bays and two external 5.25-inch bays provide high-density storage capacity. Seven expansion slots support additional controller or network cards.

Three Pre-installed PWM Fans

One 120mm PWM fan at the front and two 80mm PWM fans at the rear come fitted from the factory. They deliver directed airflow across the drive bays and motherboard area. Front-panel LEDs show power and drive activity at a glance. Two USB 3.0 ports and a keyed front lock add convenient access and physical security.

Verify Drive Mounting And Clearances

This chassis only accepts 3.5-inch drives that have three screw holes on each side; drives with two holes per side will not mount securely. The maximum CPU cooler height is 140mm, graphics cards up to 260mm long are supported, and the power supply bay fits PS2 units up to 220mm deep. Confirm your components match these limits before ordering.
