    Quality case but too noisy

    Case assembled by LDLC. Nothing to say about the product quality indeed, but noisy even though I specified that it was intended in particular for music production. So a bit disappointed. I'll have to see about replacing the fans...

    Lian Li LANCOOL III Black

    Ordered in-store with full assembly, a simple, high-quality and functional PC case with a sleek design, the glass panel adds a nice touch by showcasing the internal components.

    Very well designed.

    Spacious and airy (some walls have a mesh structure): perfect for maximum air circulation. Sober look.

    Incredible case

    The case arrived very quickly, perfectly packaged and in excellent condition.
    The Lian Li Lancool 3 is, to date, the best gamer PC case I've had the opportunity to assemble.
    The quality of the design is remarkable: almost all the components are removable, the ergonomics are very well thought out, and cable management is simple and clean.

    As for the cooling, it's simply impressive: with 10 fans installed (including 3 slim models added to the bottom section), the airflow is optimal. Honestly, you'll be hard pressed to find anything better in this range.

    To sum up: an impeccable product in every respect, and as always, impeccable service from LDLC.
