Case Lian Li O11 Vision Compact Mid-Tower Tempered Glass Black

The Lian Li O11 Vision Compact Mid-Tower Tempered Glass Black case is a mid-tower chassis aimed at mid-range to high-end configurations with an emphasis on aesthetics and good airflow. It supports ATX, mATX, and Extended ATX motherboards, giving you serious freedom in choosing components. The tempered glass side panels are ideal if you want to showcase your GPU, cooling, and RGB lighting instead of hiding them. Despite its compact name, there is room inside for a graphics card up to 408 mm and a CPU cooler up to 163 mm.

What you get
You get a case prepared for serious cooling – it supports up to 2 x 120 mm fans at the rear, 3 x 120 mm on the sides, and another 3 x 120 mm at the bottom. This allows you to build a strong intake and exhaust system, so a powerful GPU and multi-core CPU can run cooler and quieter. Inside, there are 2 x 3.5" and 2 x 2.5" drive bays, which is fully sufficient for a typical gaming or workstation configuration with a combination of SSD and a large HDD. The 7 expansion slots are standard for a full-size ATX chassis and give you a stable foundation for a large GPU plus additional cards if needed. The built-in USB 3.0, USB-C, and HD Audio on the front panel provide easy access to fast ports for peripherals, flash drives, and headphones, without having to reach for the rear panel.

• Supports motherboards in ATX, mATX, and Extended ATX formats, so you can plan even larger, loaded builds with many slots and components.
• The Middle Tower form factor balances size and functionality – enough space for powerful hardware without the case taking up half the room.
• Tempered glass side panels allow you to show off the inside of the system while providing better durability than regular glass.
• Support for up to 8 x 120 mm fans (2 at the rear, 3 on the sides, 3 at the bottom) offers serious potential for airflow and lower temperatures under load.
• Maximum graphics card length of up to 408 mm frees you from worries about whether longer high-end GPU models will fit.
• Maximum CPU cooler height of 163 mm is suitable for a wide range of tower air coolers from mid-range to high-end.
• Available 2 x 3.5" and 2 x 2.5" bays are sufficient for a combination of fast NVMe/SATA SSD plus several larger HDDs for games, projects, and archives.
• The front I/O panel with 2 x USB 3.0, 1 x USB-C, and 1 x HD Audio provides convenient connectivity for modern devices and headphones without needing to fumble at the back.
• It comes without a power supply unit, giving you the freedom to choose a PSU based on the system's actual needs and your preferred brand and certification.

Who is it suitable for
This case is suitable if you plan a gaming or workstation machine from mid-range to high-end and want the hardware to be clearly visible through the tempered glass. It is suitable for builds with a long graphics card, several drives, and serious air cooling with many fans. If you are looking for an ultra-compact system or need a huge number of drives, you should probably look at another form factor.

The strongest point of the Lian Li O11 Vision Compact is the combination of spacious interior, good cooling support, and a clean look with tempered glass, without having to compromise on GPU size or motherboard choice.
