Abstract: A standalone computer unit comprises a housing having an air intake structure and at least one component mounted within the housing which in use generates or dissipates heat. A cooling fan is arranged to generate an air flow within the housing. An elongate duct defines a closed air path from the air intake structure to the component, the duct having an inlet at or near the air intake structure and an outlet at or near the component. The cooling fan is mounted within the duct intermediate the inlet and the outlet. In a preferred embodiment, the duct comprises a portion shaped to define a cradle for receiving and supporting the fan, the fan being retained in the cradle by a resilient strap.
