The 5 Slot Mode is ideal for ITX and M-ATX motherboards and allows up to 280mm radiators to be installed at the top. If using a M-ATX motherboard, the bottom radiator can only be 240mm, but with ITX you can install up to a 280mm radiator. The mesh design on the front, top and side panels of the O11 AIR MINI have been optimized to allow maximum airflow from different sides of the case to the temperatures stable and low. The super fine mesh also acts as dust filter to avoid dust buildup inside the case. The power supply is mounted in the Lian Li O11 Air Mini as usual with four screws. Well thought-out by Lian Li: The power supply is slightly elevated and does not rest on the floor. This gives you the opportunity to neatly run cables underneath and thus reach the lower slots on the motherboard. Similar openings are also found on the upper edge. In the HDD/SSD case, the disks can be stored in two holders with the included screws. Once screwed tight, they can be put into the case. Practical test

The 7 Slot Mode has space for up to ATX motherboards. This mode will reduce radiator support – removing support for a top radiator when using any size motherboard. When using an ATX motherboard, the bottom radiator can only be 240mm, but with ITX and M-ATX you can install up to a 280mm radiator. Optimized Dust Management The mesh panels of O11 Air Mini are designed as dust filters and intake sufficient air into the chassis. Lian Li O11 Air Mini supports a motherboard up to E-ATX, however it is much more interesting when you work with a smaller Micro-ATX as that allows you to open up the top of the case for cooling hardware.Great case, enabling a very powerful system to be installed in a form factor that doesn't take over your desk.

To test the functionality of the case, we installed some hardware components. We used the following components for this purpose: Unlike the case, Lian Li does not rely on aluminum for the frame. Instead, the manufacturer uses steel here. This benefits the stability of the case. All in all, the case makes a very good impression. Especially the workmanship leaves nothing to be desired.Constructed of steel instead of aluminium, the O11 Air Mini no longer retains the initial focus on ITX builds, evident in the case's larger footprint. The undesirable feature of the unattractive bottom air filter is unfortunately still here. Despite these changes, the case has kept its cost reasonable, while its size remains relatively compact for an ATX case. A sophisticated profile is crafted through the steel mesh panel at the front, a change from the lively look of the Lian Li O11D Dynamic Mini’s glass side and front panel. However, the see-through side panel and the aluminium trim accent at the front remain. Configuration Options Undeniably, the Lian Li O11 Air MINI has become an airy case. It accommodates a lot of fans and absolutely does not get in the way of airflow. The mesh structure allows the air to flow well and looks really good to boot in our eyes. It gives the case an absolutely clean look. This is also rounded off by the glass panel on the side, which provides a view into the interior.
