Top Drop-in Mounts for the Mercury S8. These mounts are made from .090'' (2.3mm) thick aluminum to insure a very strong mounting surface. The drop-in feature provides the best way to mount radiators in the top of a PC case. The radiator, fans and mount can all be assembled on your desk and then the complete assembly can be dropped in to the top of the case. Includes screws for mounting the mount to the case.
