I purchased the Dell Optiplex 990 model, though the device list the system has sound and Dell’s spec sheet as this model with an internal speak; there was none present in the machine. Find it pretty silly to stip out an internal speaker. Also company remove the PCI video card and did even have the professionalism to at least opening on the back of the machine.  Would not recommend purchasing from this company, unless you are in the market of stripped down systems.
