Lian Li has released yet another version of its PC-O11 case. Called the PC-O11 Air, this latest variant is a high-airflow case with a bunch of fan mounts and vented panels on the front and top to help keep components cool.

The PC-O11 Air sports the same multi-chamber design as the PC-O11 Dynamic, but ups the cooling ante. Users can install up to a dozen 120mm fans in the case plus two 80mm rear exhaust fans, or less overall if going with larger 140mm fans. If you prefer to liquid cool, the PC-O11 Air has room to mount up to four 360mm radiators, one each in the top, bottom, front, and side of the chassis. And yes, Lian Li says you can install them concurrently without interference.
