Black mid-tower server chassis supporting E-ATX motherboards with four 5.25-inch and six 3.5-inch drive bays plus front USB 3.0 ports
This black mid-tower server chassis supports E-ATX motherboards and is aimed at system integrators building rack-style servers or high-density workstations. It provides four external 5.25-inch bays, one external 3.5-inch bay and five internal 3.5-inch or 2.5-inch drive bays. Front I/O includes two USB 3.0 ports for quick peripheral access.
The single specification that determines whether this chassis suits a build is its E-ATX motherboard support; larger SSI-EEB or proprietary server boards will not mount. Builders using standard ATX or micro-ATX boards can still install them, but the defining limit remains the maximum E-ATX form factor.
Five internal 3.5-inch or 2.5-inch bays handle multi-terabyte storage arrays or mixed SSD and HDD configurations comfortably. The four 5.25-inch external bays add flexibility for optical drives or hot-swap cages, while the single 3.5-inch external bay suits legacy media. Storage expansion stops when all five internal slots and five external bays are populated.

The five internal bays accept 3.5-inch or 2.5-inch drives, so you can install up to five hard disks or SSDs without using the external bays.
The two front USB 3.0 ports run at up to 5 Gbps, limited by the motherboard header and cable quality.
The middle mounts take two 120 x 25 mm PWM fans, so allow 25 mm depth per fan plus any radiator thickness if you add liquid cooling.
