Cutting down the noise emitting from a computer chassis is a constant goal of case builders, and silent cases are typically an exercise in clever engineering. The latest entry into the silent chassis market is Lian-Li
’s PC-B12, an all-black all aluminum number that employs noise-reducing foam on the front and side panels and sucks in air through a bottom intake and vents it out through a downward-facing exhaust baffle.
The PC-B12 sports two external 5.25-inch drive bays, eight expansion slots, ATX and micro ATX motherboards, and supports up to three 3.5-inch drives and one 2.5-inch drive (with a hot-swap option). There are two stock fans (140mm) on the front and one in the back (120mm), and the front I/O panel features two USB 3.0 ports and audio jacks.
You can fit graphics cards up to 360mm in length inside the PC-B12, and a CPU cooler up to 160mm can fit, as well. The price tag is $169.
Lian Li Announces Silent ATX Chassis – PC-B12
A Silent Case with Bottom Intake Vent
26 July 2012, Keelung, Taiwan - Lian-Li Industrial Co. Ltd, today announces a silent brushed aluminum ATX supported chassis – PC-B12. The PC-B12 has many features to keep noise down to minimum, including: a vent on the bottom of the chassis pulling in cool air, a downward facing exhaust baffle and noise dampening foam on the front and side panels.
The front panel of the PC-B12 has no visible vents. Instead of air entering in from the front, two 140mm fans behind the front panel pull in cool air through the 12cm wide (4.7”) intake vent on the bottom of the chassis. Four sturdy aluminum feet with rubber bottoms to reduce vibrations give ample room for air to be pulled into the bottom vent. The rear 120mm exhaust fan has an adjustable downward facing exhaust baffle on the exterior of the case with noise dampening foam that not only bounces the sound waves down, but also directs the hot air towards the floor.
The easily removable front panel and side panels of the PC-B12 both have noise dampening foam to further reduce sound from escaping the chassis.
Up to three 3.5” hard drives with an hotswap option and one 2.5” hard drive can be installed in the hard drive cage at the front of the chassis. Two 5.25” drives are easily installed thanks to the bays' tool-less mounting system.
Power supplies up to 240mm (9.4”) in length can be placed in the bottom compartment. Ventilation slits underneath the PSU with a removable pull-out filter help increase the life and performance of the power supply.
The eight expansion slots on the PC-B12 feature tool-less clamps to secure expansion cards into a locked position. VGA cards up to 360mm (12.1”) can fit in the chassis.
The I/O panel located on the top of the chassis contains two USB 3.0 ports and HD audio connections.
The PC-B12 will be available for the suggested retail price of US$169.
