Overview
The O11D Mini V2 Flow-ATX is Lian Li's compact-footprint mid-tower, shipping with 5 pre-installed 120mm reverse-blade fans, pillar-less tempered glass front and side panels, and support for ATX, M-ATX and Mini-ITX motherboards.
This case shrinks the footprint of Lian Li's O11D line while keeping room for a full-size ATX power supply, via a protruded mesh side panel. It is built around airflow rather than a single big window, with a slanted intake aimed at the GPU and brackets meant to carry heavier graphics cards.
- 5 pre-installed 120mm reverse-blade fans
- 10 degree slanted bottom panel for gpu airflow
- Supports atx, m-atx and mini-itx motherboards
- Horizontal and vertical gpu anti-sag brackets
Who it's for
Suits builders using standard ATX, M-ATX or Mini-ITX boards who want a compact-footprint case with real airflow and a glass front and side. Less suited to anyone needing a larger case with more drive bays.
Pros and cons
- Five fans pre-installed, no extra cost
- Pillar-less glass front and side panels
- Gpu anti-sag brackets support heavy cards
- Fits full-size atx psus despite compact size
- Optimized for atx back-connect boards specifically
- Drive bay count is not listed
Performance notes
The 10 degree slanted bottom panel angles intake air more directly at the GPU, while the five reverse-blade fans are shaped to push more air per fan than a standard blade. Horizontal and vertical GPU anti-sag brackets carry the weight of heavy graphics cards so it does not rest on the motherboard's PCIe slot, and a dedicated 24-pin cable bracket keeps that thick cable run out of view behind the glass panels.
