Today, we are reviewing the Lian Li PC-O11 Air, which is not to be confused with the existing PC-O11 models on the market. The Air is based on the PC-O11 Dynamic, which has the same frame but a more elaborate exterior. The Air offers a lower price tag and aims to cater to those who would rather primarily fill the chassis with air cooling.

I would like to thank Lian Li for supplying the review sample.
