Rosewill RSV-Z2850U 2U server chassis 4×3.5" 2×2.5" bays ATX 2×USB 3.0 2×80mm fans Silver/Black

Purpose-built 2U rackmount chassis

The Rosewill RSV-Z2850U is a 2U server chassis designed for rack installations that require dense storage and standard ATX motherboard support. It suits builders assembling file servers, backup targets or virtualization hosts where up to four 3.5-inch and two 2.5-inch drives must fit behind a short-depth rack rail. The 1.0mm SGCC construction and included screws keep the build straightforward for integrators and homelab enthusiasts alike.

Compatibility checks before ordering

Verify that your CPU cooler does not exceed 70 mm in height and that any add-in card fits within the low-profile 150 mm length limit across the seven expansion slots. The power supply must use the PS2 form factor and stay within 220 mm depth. Confirm your rack provides at least 430 mm width, 89 mm height and 550 mm depth clearance, and that front USB 3.0 headers are available on the chosen motherboard.

Thermals noise and power in normal use

Two 80 mm fans are pre-installed in the middle chamber with mounting points for two additional 80 mm units if higher airflow is needed. The layout directs air across the drive bays and motherboard, keeping drive temperatures steady under sustained loads. Fan noise remains modest at idle and rises only when extra fans are added or speeds are increased. Power draw is determined entirely by the installed components and the PS2 supply selected.
