Compact ATX Mid-Tower

The Lian Li O11DMIV2X is a black steel and tempered glass mid-tower case designed for ATX motherboards. It features a 10-degree slanted bottom to direct cold air toward the graphics card. The chassis includes brackets for GPU and 24-pin cable support. No fans are pre-installed.

Adjustable I/O and pillar-less glass

Builders who want flexible front-panel placement can mount the I/O panel at the top or bottom. Two USB 3.0 ports, one USB 3.2 Type C port and an audio jack are provided. The pillar-less dual tempered glass side panels give an unobstructed view. Buyers who need pre-installed cooling or a smaller Mini-ITX-only footprint should look elsewhere.

Sustained airflow under load

The extended side mesh accommodates ATX power supplies up to 200 mm long while keeping the case width unchanged. The slanted bottom continuously feeds fresh air to the GPU during long sessions. Reverse-blade fan mounts are ready for user-supplied fans to maintain steady pressure. Dimensions are 423.6 mm by 273.3 mm by 391.95 mm and the case weighs 26 lb.

商品問答

Do I need to buy fans separately since none are pre-installed?

The case ships without any pre-installed fans, so you will need to purchase and mount your own cooling fans for intake and exhaust.

Will my existing ATX power supply fit if it is 200 mm long?

Yes, the extended side mesh accommodates ATX power supplies up to 200 mm provided the power socket sits at least 12 mm from the edge.

How can I verify the 10 degree slanted bottom is directing airflow to the GPU after I build?

Check that intake air moves cleanly through the bottom mesh toward the graphics card and that GPU temperatures drop under load compared with a flat-bottom layout.
