Lian Li B4-mATX Wood Mini Tower Case Without Window - G99.B4W-WD.00

The Lian Li B4-mATX Wood Mini Tower case is a compact mATX Mini Tower chassis aimed at cleaner and more stylish builds, without unnecessary effects. The white color combined with wooden elements (walnut / beech) makes it a good choice if you want your machine to look like part of the interior, rather than a Christmas tree. Despite the small dimensions 420 x 191 x 288 mm, there is space inside for a graphics card up to 358 mm and an air cooler up to 162 mm. The panel is windowless, so the focus is on compactness, practicality, and a quieter build, rather than an RGB show.

What you get – a chassis that combines practical internal architecture and a more premium feel on the outside. It supports mATX format motherboards and offers 4 x PCIe slots, which is fine for a graphics card plus one or two additional cards (sound, network, etc.). For cooling, you have flexibility: it supports 2 x 120mm fans, plus additional 3 x 120mm or 2 x 140mm in the AeroDeck area, and the kit includes 2 x 120mm slim non-RGB – a sufficient base for decent airflow from the case. With liquid cooling, you can opt for a 360mm radiator with SFX power supply or 240mm with ATX PSU, giving you freedom for a more serious CPU. The internal storage space is covered with 1 x 3.5" and 2 x 2.5" bays – enough for one large HDD and a few SSDs.

• Compact Mini Tower mATX format, which allows for a smaller and easier-to-position build, without sacrificing space for a serious graphics card.
• Support for graphics cards up to 358 mm, which opens the possibility to fit most modern mid-range and high-end GPU models without drama.
• Maximum air cooler height of 162 mm, sufficient for mass-market tower coolers for gaming and productivity.
• Flexible cooling with an option for 360mm radiator (SFX PSU) or 240mm (ATX PSU), plus support for 2 x 120mm, 3 x 120mm (AeroDeck) and 2 x 140mm (AeroDeck) fans.
• Includes 2 x 120mm slim non-RGB fans, so you have basic cooling right from the start without needing to buy additional fans immediately.
• Support for ATX or SFX power supply with a length up to 140 mm, giving you a choice between more compact and standard PSUs, depending on the budget and configuration.
• Practical front I/O: 1 x USB Type-C, 2 x USB Type-A and 1 x Audio Jack for quick access to flash drives, peripherals, and headphones.
• A combination of 4.0mm steel and wood (Walnut / Beech) in a white case, which gives stability and a more stylish, „furnish“ look to the desk.

Who is it suitable for – for someone who wants a compact mATX machine with a cleaner, Scandinavian style, without RGB and without a transparent panel. Suitable for a gaming build in a smaller format, an office/creative system, or a home PC that does not attract unnecessary attention. If you are looking for an aggressive „showcase“ with a transparent side panel and RGB, this is not your type of case.

The combination of compact dimensions, serious support for GPU and cooling, plus the wooden accent turns Lian Li B4-mATX Wood into a very good choice if you want a tight, quiet and visually organized build. The balance between functionality and design here is precisely measured.
