Your iMac®, All-In-One or LCD monitor sits on its own stand, placed on a shelf to lower it into the desktop. Unobstructed sight lines. Sturdy keyboard/mouse tray fully retracts so the computer keyboard is out of the way when not in use. CPU bays keep computers off the top and off of the floor. The LCD can be on its own stand, giving plenty of room for use with textbooks. Grommets are used for channeling cables to the monitor, but may also be used for grommet mounted LCD arms.
