Developed in collaboration with renowned overclocker der8auer, the O11 Dynamic Mini from Lian Li is not only a smaller version of the previous O11 Dynamic case but offers enhanced functionality. This is due to a rear panel that can be adjusted to match the user's requirements. By default the full 7 expansion slots are available but this can be adjusted down to just 3 to free up internal space. Meanwhile the power supply, drives and cables are stored in a separate second chamber. All in all the O11 Dynamic Mini is a stylish case, with a compact form in aluminium and tempered glass.

The Lian Li O11 Dynamic Mini at a glance:

  • Extremely versatile thanks to a 'modular' back panel
  • Compatible with motherboards with ATX, Micro-ATX or Mini-ITX form factors
  • Front and left side panels made from tempered glass
  • Roof and right side panels made from aluminium
  • I/O panel with a single USB-C and two USB 3.0 ports
  • Support for graphics cards up to 395mm in length
  • Space for up to nine 120 mm fans
  • Suitable for SFX and SFX-L power supplies

Fantastic Flexible Case

by Nick Trimming star star star star star

This case is fantastic! The build quality is excellent and the flexibility in configuration is a really nice touch. This case easily accommodates my setup, even using a BeQuiet Dark Rock Pro. There is plenty of space and more then enough fan / radiator mounting points to cool even the hottest of systems.

Great Case To Build In

by Nick Trimming star star star star star

This is a great case to build in, with good access and plenty of room for cable management. it will accommodate some of the biggest air coolers around (I am running a BeQuiet Dark Rock Pro 4 in mine with room to spare) but also has plenty of space for an AIO or full custom loop water cooling. I would recommend this to anyone who wants a sleek look, while still being able to cram loads of components and cooling into their case.


by Rebecca Lees star_border star star star star

I loved this smaller case, I love the "no space" look. It looks super clean. Make sure you plug all your headers etc in before fitting fan, especially if you go for 7 slot build. It gets a bit cramped in there with 9 fans. Looks braw when done tho!
