This desk-side (9U 900mm Depth Rack-mount Server Cabinet – Black), floor mounted server cabinet is designed for small/medium business, research, academic, and studio environments, where a dedicated server room is not practical and excessive noise is unacceptable. This aluminum and steel framed cabinet features lockable front, side, and rear access doors/panels for security. The vented doors combine with the optional cooling fans (up to six 120mm fans on the top panel) to provide excellent air circulation, keeping your servers and other equipment at optimum operating temperature.
