Changing Between Tower and Desktop Modes

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before opening the cover.

NOTICE: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your computer’s electronic components. You can do so by touching an unpainted metal surface on the computer.

NOTICE: To avoid damage to a drive, do not set it on a hard surface. Instead, set the drive on a surface, such as a foam pad, that will sufficiently cushion it.

NOTE: To change your computer’s orientation from either tower to desktop or desktop to tower, you must use an optional kit available from Dell. See "Product Information" on page 291 for more details on ordering from Dell.

With the purchase of an optional kit from Dell, you can change the configuration of your Dell Precision computer between desktop and tower modes.

NOTE: The tower configuration supports a third SAS or SATA hard drive in the FlexBay. The desktop configuration only supports a third SATA drive.
