A hard disk drive case has a base, a cover and a fan assembly. The base has an inner surface, a sidewall and an outlet formed through the sidewall of the base. The cover is mounted onto the base and has an inlet formed through the cover. The fan assembly is mounted on the inner surface of the base, is surrounded by the sidewall of the base and has a bracket and a hood. The bracket has an airway and a fan. The airway is flared and communicates with the outlet. The fan is mounted in the airway. The hood corresponds to and covers the airway to form a chamber communicating with the outlet and has a hole defined through the hood, corresponding to the fan and allowing the fan to extract air from the inlet and to guide air toward the outlet efficiently.
