The Lian Li O11 PC-011 AIR in detail:

The Lian Li PC-O11 AIR has been designed with enthusiasts in mind. Lian Li worked with renowned PC modder der8auer to create a stylish and attractive case that is also optimised for performance.

The Lian Li PC-O11 AIR is a tower case and can hold a motherboard up to E-ATX configuration. At its core is a dual chamber enclosure. This helps greatly with cable management and to keep your build neat and tidy. This is particularly useful as Lian Li have included a tempered glass side panel so you can show off your components.

The front of the case features a prominent plastic grill that stretches from the front panel to the case's roof. The grill looks great with any LED lighting installed internally being visible and is very practical. It allows for serious airflow with room for up to twelve 120mm fans, which can be distribute across the case's front, bottom and roof panels as well as beside the motherboard.

Lian Li have considered the details, they have included two 120mm PWM fans and there is room for multiple storage options such as up to six 2.5” SSDs or three 3.5” HDDs. The front facing I/O panel includes two USB 3.0 Type-A ports and one USB 3.1 Type-C port.

Incorrect description

The description of this product has the dimensions as Dimensions: (W)27mm x(H)465mm x(D)476mm this is wrong the real dimensions are (W)272mm x (H)465mm x (D)476mm. This was most likely a typo but it needed to be corrected.
