Lian Li announces a new case model, the B4. This case features a compact design with a volume of just 21.3 liters, as well as wooden accents and the option to mount it vertically. Additionally, it includes support for 360mm water-cooling radiators as well as for large, four-slot graphics cards over 35 cm in length. In short, this is a case that really catches the eye!
B4: Lian Li’s new masterclass!
Compact, highly compatible, and can be oriented vertically!
With this case, Lian Li offers a flagship model measuring 191 (W) x 420 (D) x 288 (H) mm. Despite its compact design, it can accommodate robust setups, as there’s enough space to install both mini-ITX and micro-ATX motherboards. Better yet, graphics card compatibility isn’t an issue, as it supports models up to 358 mm in length, all across four slots. In terms of cooling, there’s room to install a 360 mm AIO or a large CPU cooler ranging from 162 to 168 mm in height. As for the power supply, Lian Li allows for the installation of an ATX unit, although an SFX power supply is recommended to maximize compatibility with AIOs or graphics cards.
The cooling options highlight the ability to mount up to nine 120 mm fans or four 140 mm fans. In any case, it comes with two 120×15 mm fans pre-installed.
But what sets this case apart is its ability to be installed vertically. In fact, you simply need to reposition the power cable to stand it upright. Additionally, Lian Li offers an optional “AeroDeck” front panel that improves cooling, particularly for the graphics card.
Pricing:
This new case was launched on June 26, priced at €69.99 for the black version and €74.99 for the white mesh version. The wood models, featuring wooden accents, are priced at €84.99 in black and €89.99 in white, while the Aero Deck is available for €29.99.
