In order to gain access to the inside of the S-9000, four 6-32 screws must be removed from the back of the case chassis. An inside view of the case interior reveals plenty of room to handle a wide variety of standard and large sized motherboards. One theme which seems to be missing in most server cases of this size is the option for a slide out motherboard tray. The motherboard tray which is provided with the S-9000 is riveted directly to the chassis frame, which means all installation of hardware components must be done from inside the case.
