general information

general information


The LIAN LI O series chassis will be a hit as they look incredibly cool. They are open-air cases with a full aluminum design. The only part that's not made of aluminum is the see-through, tempered glass side panel, which allows you to see the full guts of the PC. The O series chassis is wall-mountable, and can be placed in a vertical or horizontal position on a desk.

Whether in hardware compatibility, expandability or cooling performance, the slim LIAN LI O series chassis doesn't make any compromise. Generous internal space accommodates large-sized PC components. It also provides multiple options to install your 3.5" and 2.5" HDDs. The airflow cooling solution works together with AIO water-cooling solution to keep your system running in top condition.

The new O series includes four chassis: the PC-O5 (with a single preinstalled fan only), and PC-O5S, PC-O6S and PC-O7S (with support for AIO water-cooling system).

Show Off Your Hardware in Slim Profile Chassis

The new LIAN LI O series chassis reflects the feedback of the worldwide DIY community, and features oversized tempered glass windows, PCI riser cards, and sleek aluminum construction. Through the oversized tempered glass window, onlookers can see the entire build unrestricted. Graphics cards are installed parallel to the motherboard, keeping the chassis slim, thanks to the included PCI riser card and extension. An anodized aluminum shield covers the hard drive cage to keep a super clean look.
