The The CTE C700 Air, a specially designed E-ATX mid tower chassis from the new CTE form factor series, was engineered to provide optimal thermal efficiency and maximum airflow to ensure that critical components of your build are provided with adequate cooling. To achieve this the CTE C700 Air can support up to a 420mm AIO radiator not only at the front but also at the rear of the chassis. Three 140mm CT140 fans are pre-installed.
