Lian-Li Industrial Co. Ltd has launched the PC-B70 and PC-B71 full tower chassis. Both cases are made from aluminum sheet metal, and have plenty of room for large numbers of hard drives (HDD) while still incorporating the classic brushed aluminum style and functional design for ease of use and stunning good looks. The PC-B70 has a left side access HDD cage that can accept seven (7) full 3.5 inch hard disk drives. The Hard drives are secured by means of a removable HDD bracket with patented vibration reduction system. While the five Optical bays are an added bonus (the last ODD can be used as 3.5”disk reader). Both towers stand at 220 x 595 x 590mm (W,H,D). The PC-B71 is different via the lower part of the front bezel which has an integrated HDD Hot swappable SATA cage with a front facing securely lockable door. The HDD Cage is cooled via two (2) 140mm blue lit LED fans. The fans are filtered with removable, washable nylon filters. The easy access to the hot swap Raid HDD backplate via the front lockable door makes the PC-B71 convenient while still retaining the good looks found in every Lian Li chassis. Tool-less storage design The PC-B71 HDD Cage houses 7x 3.5” hot swappable HDD bays supporting RAID arrays and for those who change HDD’s frequently, keeping your rig cool and well ventilated but also segmenting the various parts for optimal cooling and functionality. Anti-vibration couplings are integral to the structure and concept, with simple elegance and convenience foremost in the design. The PC-B70 HDD cages are also easy to use and tool-less. The HDD’s will fit snugly with secure brackets that are mounted conveniently and easily. They slide into the HDD cage and are clipped into place to prevent movement and vibration from spreading throughout the chassis while making the HDD’s easy to remove and swap out. Both chassis have easy to use tools-l ess CD-ROM claspers and tool-less PCI card retention systems. Noise reducing side panels Both chassis are fitted with tool-less clips for easy installation and removal of the side panels. The side panels are covered with sound insulation foam and anti-vibration rubber strips on the edges sealing the connection between the side panel and case.

The seven (7)- PCI slots have a grill structure to improve air through flow. The Power Supply can be positioned on top or at the bottom In both cases the PSU bay can be either on top or at the bottom, with an adjustable bracket to secure extra long PSU’s in place.
