The Top, Bottom, and Rear Panels
The Antec One comes with a 120 mm fan installed on its top panel, using a standard three-pin fan power connector. This fan spins at 1,200 rpm and produces an airflow of 42.6 cfm and a noise level of 23.7 dBA.
The bottom panel has an air filter for the power supply fan, but there is no air filter for the optional bottom fan.
The rear panel and the interior of the Antec One are painted black, which is great to see on an entry-level product.
On the Antec One, the power supply is installed at the bottom of the case.
The case comes with a 120 mm fan installed on its rear panel, identical to the one available on the top panel.
This case has seven expansion slots with solid covers. Only one of the covers is reusable; the others you need to toss away after they are removed from the case.
Let’s now take a look inside the Antec One.
