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.
