Dell OptiPlex Optical Drive Bracket

This new Dell mounting bracket secures an optical disc drive inside OptiPlex 790 and 990 Small Form Factor desktops. It acts as the carrier rail that holds the drive firmly in the chassis drive bay. The part carries Dell part number C4GN7 and is supplied as a standalone component. It is designed specifically for the optical drive slot in these SFF models.

Fits OptiPlex 790 and 990 SFF Only

This bracket suits owners of an OptiPlex 790 or 990 Small Form Factor system who need to install or replace an optical drive caddy. It will not fit OptiPlex tower, mini-tower or micro chassis variants. Buyers with other Dell models or non-Dell systems should look for the bracket designed for their specific chassis. The part addresses the optical drive bay exclusively.

Dell Part Number C4GN7

The decisive specification is the Dell part number C4GN7, which confirms compatibility with the OptiPlex 790 and 990 SFF optical drive bay. Matching this number to your service manual or existing bracket ensures the mounting points align correctly. No other part number will guarantee the proper fit for this specific drive carrier. Verify C4GN7 before ordering.
