Compact ATX Mid-Tower

The Lian Li O11D Mini V2 Flow is a compact ATX mid-tower built around a steel frame with tempered glass side panels. It targets builders who want a small-footprint case that still accepts a standard ATX motherboard and full-size power supply. The black finish and ARGB lighting suit clean, showcase-style builds.

Five Pre-Installed Reverse Blade Fans

Five 120 mm reverse blade fans come mounted at the bottom and side, angled to push cool air directly toward the graphics card. A ten-degree slanted bottom panel improves intake efficiency without extra parts. The bundle removes the need to buy and install separate case fans for a high-airflow layout.

Steel and Tempered Glass Build

The chassis uses steel construction with two tempered glass side panels for durability and component visibility. An extended side mesh allows ATX power supplies up to 200 mm long while keeping the case width unchanged. Front I/O includes two USB 3.0 ports, one USB 3.2 Type-C port, and an audio jack, with the I/O module movable to the top or bottom. Bundled GPU and 24-pin cable brackets reduce strain and keep routing tidy. Builders needing more than two glass panels or a different motherboard form factor should look elsewhere.

Questions about this item

How often should the five pre-installed 120mm reverse blade fans be cleaned or replaced?

Dust the fan blades and mesh panels every few months with compressed air; the fans use standard 120mm mounts so they can be swapped individually if a bearing ever becomes noisy.

What thermal limit appears first when the GPU runs at full load for hours in this chassis?

The 10-degree slanted bottom feeds cool air straight to the graphics card, so the GPU’s own temperature target is reached before the case airflow becomes a bottleneck.

How loud and hot does the system get when all five 120mm fans run continuously at typical speeds?

Five reverse-blade fans moving air through mesh side and bottom panels keep internal temperatures low while noise stays at a moderate hum suitable for a desk environment.
