The new Lian Li PC-O11 Air is an update to the PC-O11 series to allow more airflow through the chassis. The PC-011 Air has five locations for air intake and exhaust and is able to accommodate a total of twelve 120mm fans and multiple 360mm radiators inside the Mid-Tower sized case. Lian Li dubs the case as the ultimate platform for cooling.

On the outside, the Lian Li PC-O11 Air changes some of its panels (compared to the PC-O11 Dynamic) in order to accommodate more fans in the system and create a better environment with improved airflow. Instead of the sealed glass fascia, the new panel is perforated to let air in and allows for 3x 120mm fans. As far as connectivity goes, the front panel consists of two USB 3.0 ports as well as a USB 3.1 Type-C port along with headphone and microphone jacks and the power button.

The other nine 120mm fan mount points are on the top and bottom as well as the on the inside of the case mounted on the right side of the motherboard tray/baffle. With so much potential airflow, dust prevention was considered and the front, bottom, top, and side panels all use magnetic dust filters to help that cause and keep the dust out. Up to three 360mm radiators can fit inside the case in either a top/bottom/front or top/bottom/side configuration. Using the front mount blocks the side mount location. In addition to the 12 potential fans, two 80mm mounts are found on the back.

Internally the structure looks strikingly similar to the PC-O11 Dynamic on the inside, with its dual chambered setup and plethora of fan mount locations. The chassis is able to support microATX, ATX, and E-ATX sized boards along with the ability to use a heatsink up to 155mm. This height will fit the vast majority of air coolers on the market, but will not fit monsters like the Noctua NHD-14. VGA card length is up to 420mm which should fit just about every modern graphics card.

Cable management should be fairly easy with the angled motherboard tray and back side cable management bar to conceal any mess from cables. A unique feature inside the PC-O11 Air is the ability to use two different power supplies. If a second power supply isn't needed, the mount location can be swapped from top to bottom.

On the storage side of things, a total of six 2.5-inch devices can fit inside with two on the bottom panel in the main chamber, and four more 2.5-inch devices (or three 3.5-inch) can be housed in the dedicated storage and power chamber behind the motherboard.
