3U rackmount chassis with sliding rails

This 3U server chassis fits a standard 19-inch rack and ships with a 20-inch sliding rail kit for straightforward installation. The silver aluminium front bezel includes a key lock, while the main body uses 1.2mm zinc-coated steel from Japan. It accepts ATX or microATX motherboards up to 12 by 9.6 inches.

Seven expansion slots and dual PSU support

The chassis provides seven low-profile expansion slots and accommodates either 1U or 2U power supplies, letting builders match the power subsystem to their workload. A single 60mm fan is fitted as standard, with mounting points for one additional 60mm and three 80mm fans when the optional DD-FANGUARD-8 bracket is added.

Front USB 2.0 ports and drive bay mix

Two front-access USB 2.0 ports give quick peripheral connectivity without reaching to the rear. Internal storage capacity comprises two 3.5-inch bays, one internal 3.5-inch bay and four 5.25-inch bays, while front-panel LEDs show power, drive activity, temperature and fan status when the optional TC-ISF08 sensor board is installed.
