4U rackmount server chassis

The Rosewill RSV-R4000U-SK is a 4U rackmount server chassis built for ATX, Micro ATX, Mini ITX and CEB motherboards. Its SGCC construction provides a black and silver enclosure suited to dedicated server builds that need high internal drive density.

Eight 3.5-inch bays and three 5.25-inch bays

Eight internal 3.5-inch drive bays and three external 5.25-inch device slots give ample room for storage arrays and optical or backup units. Two Sudokoo SK120 PWM fans run at 500 to 3000 RPM alongside two rear 80mm fans, all pre-installed for immediate airflow.

Locking front panel with USB 3.0

A built-in front panel lock secures drive access while LEDs show power, drive activity and two LAN links. Front-mounted USB 3.0 ports allow quick peripheral connection. The chassis accepts CPU coolers up to 117mm with the GPU holder fitted or 152mm without, graphics cards to 270mm and ATX power supplies to 220mm depth.

Questions about this item

Will the Sudokoo SK120 PWM fans or the rear 80mm fans need replacement under sustained load?

The chassis includes two front 120mm Sudokoo SK120 PWM fans rated 500-3000 RPM and two rear 80mm fans. All four are pre-installed; fan lifespan depends on operating conditions and dust environment.

Which thermal limit is reached first when all eight 3.5" bays and seven expansion slots are populated?

Maximum CPU cooler height is 117mm with the GPU holder installed or 152mm without it, and GPU length is capped at 270mm. These clearances become the constraining factor before airflow does.

How much noise and heat should I expect from the four included fans running continuously?

Front Sudokoo SK120 PWM fans spin at 500-3000 RPM ±10%; rear 80mm fans run at fixed speed. Acoustic output varies with PWM duty cycle and system load, but the design targets quiet cooling.
