    A must

    This case is undoubtedly the best I've had in the 25 years I've been building computers. Lian Li has done an excellent job: the case is very well designed, there's plenty of room inside while still being compact, and the whole thing exudes quality.

    Top gear

    The advice and the quality of the equipment were perfect. Excellent value for money. I'm happy with the way the equipment is used on a daily basis, particularly its quick response when used for graphics.
    The delivery (collection from the shop) was disappointing: very few details, no contact with the technician and no power-up to check. What's more, I didn't want a partitioned drive. No listening at all!

    Small size and large capacity

    It's a simple tower with style.
    It's perfectly ventilated.
    It takes up very little space, and I'm even pleasantly surprised by its small width.

    I'd recommend it.
