Open rack is a cost-effective storage device. In general, open racks are more affordable and cost less to ship than enclosures. There is no need to worry about installing cabinet doors or side panels, so installing an open rack is a much easier task. Enclosed racks create an environment where heat accumulates. On the other hand, open racks ensure that airflow is not blocked. Open rack design is more convenient for operation and maintenance.
These racks are widely used in data centers, server rooms, and for a variety of IT applications
However, it is also important to consider that open racks may expose equipment to dust and physical damage more so than enclosed racks, so they may not be ideal in all settings.
