I have 8 of these complete systems that were going to be installed in a Dr's Office. These units were left over from the project. One box of each part was opened to take the picutes, all other boxes are factory sealed. All units include all the hardware for installation. The keyboard tray is the ergo model with the extended mouse trays. Im willing to let them go at $125.00 each or can work out a better deal if you want more than one. The model number of each piece is located on the box in the picture.
