A storage rack for supporting a server chassis in a storage cabinet. The storage rack includes vertical supports and outer rails attached to the vertical supports. The storage rack includes first and second middle rails supported by the first and second outer rails such that the middle rails may slide upon the outer rails. First and second inner rails slidably engage with the first and second outer rails and are typically attached the sides of the chassis. The storage rack further includes first and second magnetic guide assemblies that are each attached to an exposed end of one of the first and second inner rails. Each of the magnetic guide assemblies includes first and second magnetic alignment elements extending outward an alignment distance from the exposed end of the corresponding one of the inner rails such that magnetic forces assist both in initial alignment and in engagement.
