4U Server Chassis for Storage Builds
The Rosewill RSV-R4000U-SK is a 4U rackmount case built for systems that need dense hard-drive capacity. It fits ATX, Micro-ATX and Mini-ITX motherboards and supports standard ATX power supplies up to 220 mm long. The SGCC steel frame provides a rigid platform for server or workstation deployments.
Eight 3.5-Inch Bays and Sudokoo PWM Fans
Eight internal 3.5-inch bays let you install a large storage array, while three external 5.25-inch slots remain free for optical drives or hot-swap cages. Two included Sudokoo SK120 120 mm PWM fans at the front spin between 500 and 3000 RPM, and two 80 mm rear fans exhaust heat. Front-panel LEDs show power, drive activity and dual LAN status.
Expansion Limits and Cooling Headroom
Seven expansion slots accommodate full-length cards up to 270 mm, though the GPU holder reduces maximum CPU cooler height to 117 mm; removing it raises clearance to 152 mm. Two USB 3.0 ports on the front provide quick peripheral access. A keyed front-panel lock secures the drive bays against unauthorised removal.

שאלות על הפריט הזה
How often should the two included Sudokoo SK120 PWM front fans be cleaned or replaced?
The Sudokoo SK120 PWM fans spin at 500–3000 RPM; clean dust from their blades and filters every three to six months and replace a fan only if bearing noise appears or airflow drops.
Which limit appears first when the chassis runs continuously with eight drives and a full-length GPU?
The 270 mm maximum GPU length and 117 mm CPU cooler clearance with the GPU holder installed are the physical constraints reached before thermal limits.
What noise and heat levels should be expected from the two 120 mm front and two 80 mm rear fans during all-day operation?
Front fans run at 500–3000 RPM PWM speeds while rear 80 mm fans spin constantly; together they move high airflow with low noise under typical server loads.
