Lian-Li Industrial Co. Ltd, has launched the O Series open-air, wall-mountable chassis: PC-O5X, PC-O5SX, PC-O6SX and PC-O7SX. Previewed to the worldwide technology community in its prototype stage, the O Series chassis final design reflect the feedback of the DIY community, and feature oversized tempered glass windows, a PCI riser cards, and sleek aluminum construction.

Four Open-Air, Wall-Mountable Aluminum Chassis

The new O series includes four chassis: the mini-ITX PC-O5, the mini-ITX PC-O5S, the micro-ATX PC-O6S, and the ATX PC-O7S. These aluminum constructed cases all feature a similar design and aesthetic differing in their hardware compatibility.

Show Off Your Hardware in Slim Profile Chassis

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. A black anodized aluminum shield covers the hard drive cage to keep a super clean look.

Customizable Storage Options

The O Series chassis give builders several options for storage installation. Hard drives can be mounted in the hard drive cage, hidden by an anodized aluminum shield, directly mounted on the motherboard tray, or installed on a removable bracket behind the motherboard.

Water Cooling Support

The PC-O5S, PC-O6S, and PC-O7S support AIO water cooling systems. The “S” suffix in the aforementioned models denotes water cooling compatibility. The PC-O5S supports radiators up to 240mm, while the PC-O6S and PC-O7S supports 360mm radiators.

Versatile Placement

The O Series cases can be mounted to the wall, placed on a desk in the vertical position using the included aluminum stand with rubber grip, or arranged horizontally on four attachable feet with rubber padding.
