A computer case retention structure includes a cover and a base. The base has a bottom plate and a guided way with a protruding hook. The cover has at least one side plate, a first and second elastic blades are disposed on the side plate. A protrusion is extended downward from a tip of the second elastic blade to slide against the guided way. For fixing the cover onto the base, the protrusion slides over the protruding hook and then stopped by the protruding hook, so that the cover is fixed onto the base without being moved relative to the base. For removing the cover, a release element disposed on the first elastic blade is pressed to bend the first and second elastic blades, separating the protrusion from the guided way. Then the cover can be removed from the base without the protrusion being stopped.
