A cable connector assembly useful for properly aligning/positioning and retaining (during connecting and disconnecting) a number of connectors for computing devices. The assembly uses left and right side walls with flexible and resilient connector engagement members that provide at least some amount of outward “give” or movement to facilitate assembly but are designed to spring back into place after insertion of the connectors. The engagement members of the left and right side walls may each take the form of a leaf spring that can be flexed a distance outward but then spring back to or towards a non-deformed state to mate with and apply an inward retention force against the adjacent connector. The assembly includes removable and rotatable middle walls or dividers that are placed on posts extending upward from the inner surface of the assembly's base and allowed to rotate about the posts during the assembly process.
