A 2U rackmount chassis holding four 3.5" drives, one 5.25" bay, and two pre-installed 80 mm fans for Micro-ATX builds
The Rosewill RSV-Z2700U is a 2U rackmount chassis built for Micro-ATX or Mini-ITX motherboards. It suits home labs, small business servers, or edge deployments that need dense storage in a standard rack footprint. The SGCC steel construction provides a sturdy enclosure for continuous operation. It is not for builders needing ATX or E-ATX board support or more than four low-profile expansion slots.
Four internal 3.5-inch drive bays accept 3.5-inch or 2.5-inch drives, giving ample room for a storage array or mixed SSD and HDD sets. A single external 5.25-inch bay remains for optical media or a front-access accessory. The 150 mm maximum power supply length limits choices to compact PS2 units, and the 70 mm CPU cooler ceiling rules out most tower coolers.
Four PCI expansion slots accommodate low-profile cards up to 150 mm long, fitting RAID controllers, NICs, or GPU compute cards. Two pre-installed 80 mm PWM fans at the front push air through the drive cage and over the motherboard. Front-panel USB 3.0 ports provide quick peripheral access without reaching the rear. Builders needing full-height cards, long GPUs, or liquid cooling must choose a larger chassis.

The chassis accepts Micro-ATX and Mini-ITX boards and supports PS2 power supplies up to 150 mm long, so your current parts will install without modification.
The front panel includes power, HDD and LAN LEDs; watch the HDD LED for drive activity and feel airflow at the front vents to verify the 80 mm fans are moving air.
The package includes the server case, screw sets and other accessories; the four 3.5" bays also accept three 2.5" drives using the supplied hardware, so no extra screws are required.
