The Lian Li O11 Air is a PC case, not a computer. It is a mid-tower chassis that holds ATX, Micro-ATX or Mini-ITX motherboards and has space for fans and radiators. The O11 AIR MINI variant is a smaller case built around airflow. Thinvent does not make PC cases. The closest Thinvent alternatives are our Treo Mini PCs, which are complete small-form-factor computers that can be used where a compact, ready-to-run system is needed in place of a case plus separately sourced components.

Key differences
-
The Thinvent Treo Mini PCs are complete computers with a processor, memory, storage and operating system included. The O11 Air Mini is an empty case that needs motherboard, processor, memory, storage and power supply added.
-
The Thinvent Treo with Intel Core Ultra 5 125U has up to 2 TB SSD and dual Ethernet ports, which the case does not provide.
-
The Treo with AMD Ryzen 5 7430U supports up to 64 GB RAM, while the Intel Core Ultra 5 125U model is configured with 32 GB DDR5.
-
The Lian Li O11 Air Mini is built for airflow and custom cooling layouts, a design focus that a compact Mini PC does not aim to match.
-
We could not confirm the O11 Air Mini's case dimensions or drive-bay count from the facts available, so those are not compared here.
Which one should you choose?
Choose a Lian Li O11 Air Mini if you are building a custom PC and want a case with a large fan and radiator layout. Choose a Thinvent Treo Mini PC if you need a compact, ready-to-run computer with the processor, memory, storage and operating system already included, for desk, kiosk or office use.
