Small Increase, Big Changes
The Lian Li O11D Mini V2 is an update of the original O11D Mini PC case. It features an increased volume of 2L, measuring 391.95 x 273.3 x 423.6mm (HxWxD). As a result, Lian Li has been able to make some major changes to the internal structure for better hardware compatibility.
Within the main chamber, the O11D Mini V2 has ample space for motherboards ranging from Mini-ITX to ATX form factors. New to the O11D Mini V2 is support for the latest rear-connector ATX motherboards, such as ASUS BTF and MSI Project Zero.
Additionally, this backplate boasts two sets of stand-off mounting points, letting you install your motherboard at one of two heights. By doing this, the O11D Mini V2 offers greater flexibility when it comes to radiator support, facilitating 240, 280, and 360mm radiators up to 92mm thick. Plus, with five PCIe slots and 400mm GPU clearance, you’ll have plenty of room to install a full-sized graphics card no matter which configuration you choose.
Optimised Cooling
The O11D Mini V2 redesign also delivers fantastic cooling performance. The base panel is angled 10°, which directs any airflow from fans installed here directly into your GPU’s cooler. Internal testing against a Lancool 207 found that by doing this, GPU temperatures are reduced by up to 3.1°C!
Furthermore, the O11D Mini V2 boasts nine mounting points for 120mm fans. These can be laid out with three at the top and bottom of the case, two on the side panel, and one at the rear. For fantastic performance out the box, the O11D Mini V2 Flow comes with five pre-installed reverse airflow fans on the bottom and side panels.
The O11D Mini V2 also includes two tool-less covers, which can be inserted alongside any side mounted fans. When installed, these prevent air from escaping through the side panel, concentrating airflow across your core components.


Making it Your Own
The Lian Li O11D Mini V2 is an excellent choice for building your dream gaming PC, boasting several innovations for customisation and minimal clutter. To start with, the front I/O can be positioned in one of two locations, either at the top of the case above the side air intake, or at the bottom inside the front foot.
Additionally, the O11D Mini V2 comes with both a vertical and horizontal GPU bracket. As such, you can freely position your graphics card however you’d like. Plus, there are two anti-sag brackets included, one for each orientation, to give you peace of mind that your GPU will be fully supported at all times.
Whichever layout you choose, the cable management features will ensure your gaming PC is clutter-free. The rear chamber offers ample room for cable routing and comes with nine Velcro straps. These are designed to collect excess cables into easily managed bundles and are placed along the routing paths to your hardware. The O11D Mini V2 is also equipped with a dedicated 24-pin ATX power cable bracket, which holds your cable firmly in place to reduce strain on its connector and present a super-clean aesthetic.
Easy to Maintain
Keeping your PC clean will be simple with the Lian Li O11D Mini V2 PC case. Both the top and side mesh panels feature ultra-fine mesh filters, facilitating outstanding airflow while blocking larger debris from entering.
At the bottom of the case, there is a removable dust filter. Also equipped with fine mesh, this filter quickly slides out for convenience. Both the larger panels and removable dust filter are easy to clean, using a lint free cloth.


Simplified Building
The Lian Li O11D Mini V2 is packed with innovations to simplify the PC building process. For example, the top and bottom fan brackets are removable. As such, you can mount your chosen fans on the brackets, manage their cables, and then return the bracket to the case. In addition to this, both the front and side glass panels can be removed, offering easier access to all corners of the O11D Mini V2.
