4U Rackmount Chassis with 12 Hot-Swap Bays

The Rosewill RSV-L4412U is a 4U rackmount server chassis built for environments that need dense, accessible storage. It accepts up to twelve 3.5" or 2.5" SATA and SAS drives in hot-swap trays and fits ATX, E-ATX, Micro ATX, or Mini ITX motherboards. Seven full-height expansion slots and two front USB 3.0 ports complete the core feature set.

Sustained Cooling with Five Pre-Installed Fans

Three 120 mm front fans and two 80 mm rear fans ship installed, delivering continuous airflow across the drive cage and motherboard. The layout keeps inlet and exhaust paths separate so temperatures remain stable during long rebuilds, backups, or compute jobs. Fan noise stays low enough for office-adjacent racks while still moving enough air for fully populated bays.

Clearances and Power Supply Fit

Maximum CPU cooler height is 117 mm with the GPU holder fitted or 152 mm without it. Graphics cards up to 320 mm fit with the middle fan in place, or 400 mm if that fan is removed. The PS2 power supply bay accepts units up to 220 mm deep. Verify your cooler, card, and PSU dimensions against these limits before ordering.

Questions about this item

How loud are the three 120 mm front fans and two 80 mm rear fans when the chassis runs continuously?

Five fans are pre-installed — three 120 mm units at the front and two 80 mm units at the rear — providing continuous airflow across the drive bays and motherboard without published decibel figures.

Which motherboards and power supplies fit the RSV-L4412U without extra parts?

The case accepts ATX, E-ATX, Micro-ATX and Mini-ITX boards, and supports a standard PS2 power supply up to 220 mm long; both are required for the system to operate.

Will a full-height PCIe card up to 400 mm long fit alongside the middle fan bank?

With the middle 120 mm fans installed the maximum graphics card length is 320 mm; removing those fans extends clearance to 400 mm while retaining the front and rear fans.
