Drive bay layout and board support

The Rosewill RSV-R4200U is a 4U rackmount server chassis built for high-density storage. It provides eleven internal 3.5" drive bays plus three 2.5" positions, or fourteen 2.5" bays in an alternate configuration. Motherboard compatibility covers ATX, E-ATX, Micro ATX, Mini ATX and SSI CEB form factors. Four PWM fans are pre-installed for front-to-rear airflow.

Who this suits and who should look elsewhere

This chassis suits builders who need many 3.5" drives in a standard rack footprint with CEB board support. It is not for users who require hot-swap drive trays or tool-less sleds. Buyers with 3.5" drives that only have two screw holes per side cannot mount them securely. Anyone needing graphics cards longer than 260 mm or CPU coolers taller than 140 mm should choose a larger enclosure.

The specification that decides fit

The critical constraint is the 3.5" bay mounting standard: the eleven bays accept only drives with three screw holes on each side for a three-point connection. Drives with two screw holes per side will not fit. Verify your drive hole pattern before purchase.

Questions about this item

Which motherboard form factors fit the RSV-R4200U so I can use my existing board?

The chassis accepts ATX, E-ATX, Micro ATX, Mini ATX and SSI CEB motherboards, so any board matching those standards will mount directly.

Will the pre-installed 120 mm and 80 mm PWM fans connect to my current motherboard headers?

Yes, the four PWM fans use standard 4-pin connectors that plug into any motherboard fan header for automatic speed control.

How can I confirm the chassis is cooling properly after assembly?

Watch the front power and HDD LEDs for normal operation, then verify fan speeds in BIOS or software and check that drive temperatures stay within expected ranges.
