Lian Li - The Ultimate Craft

• "Quality" is always the essence of Lian Li's products since 1998 when Lian Li offered the first all aluminum chassis to the market. Since then, Lian Li exemplifies the same quality standards, ensuring durability and craftsmanship come first. All products are manufactured in Taiwan and distributed to worldwide markets.
• Lian Li put a lot of effect to bring out the quality of our products, there are hair-line brush finishing and with anodized on aluminum surfaces, and all the sharp edges has been removed.
• In 2010, the new TYR X series, with new style, new structure, and better quality! There are also protection kit to protect user’s hand and cables. When come to users’ safety, all the detail counts.

LIAN LI - Excellent Design

• User Interface is very important key in Lian Li chassis. The external fixture, user interface, and the internal structure all has been test to meet Lian Li’s high quality standard. 2010 Lian Li launched the new TYR series, PC-X900, with all aluminum alloy chassis, round edge design with stylish look. PC-X900 has hair-line brush anodized aluminum finishing.
• The cutting edge tool-less design is an important key feature in 2010 Lian Li cases. Lian Li designer considered end user requirements, like those who need to build systems faster, or swap out components often. The brand new tool-less modules can make Lian Li users’ life much more convenient.
• The TYR PC-X900 is the case which functionality and style converge.Open the side panel with the tool-less latch, HDD racks, 5 x120mm silent intake fans with filter, top mounted multi-media I/O ports, and the graphics card holder have been redesigned – because when it comes to your comfort, every detail counts.

Fine Craft Products

• The PC-X900 has two-heat zones design to have better thermal solution and tidy up internal space.
• The new internal layout has the motherboard on middle level, which allows for easier access to the motherboard as well as more room above, thus larger CPU coolers can be used. To install the power supply unit, just slide the power supply unit throguh the opening at the rear of the case, and there are room for 180mm long power supply. If user need more space, there is a power supply extension kit.

Silent Performance

• The fans are mounted with Lian Li’s anti-vibration fan mounting system; the rubber ring grommet absorbs the vibration, keeping the case silent.
• The new 5.25” bay tool-less mounting incorporates a mounting bar equipped with rubber padding. After closing the mounting bar, the rubber pad pushes and holds the 5.25” device in position to both secure and absorb vibration from the device.
• The aluminum PCI tool-less mounting module is equipped with a rubber pad which can hold the graphics card firmly while closing the gap found in the PCI bracket and PCI slot to reduce noise from escaping air and furthermore reduce vibrations.
• The PC-X900 features Lian Li patented Anti-virbation HDD cage, which allow user to fit seven of 3.5" HDDs. It is easy to use, no tool required, simply using the special thrumb screw to secure the anti-vibration rubber ring to the HDD, and slide the HDD into the cage.
• The power supply has rubber pads for both insulation and support. The mounting clip is also aligned with rubber to reduce vibrations but also and also secure the PSU without scratching the painted surface.
• Lian Li is equipped EMI spring at the bottom of the hard disk rack, so that keep quiet and shock-absorbing hard disk, and hard drive rack is still easy to install and remove.
• Chassis has anti-vibration grommets to support the motherboard tray. The anti-vibration spring clips on the chassis push against the side panel to reduce the chance of vibration, while enhancing the perfect fit between the removable parts.

Thermal Solution

• The PC-X900 features two-heat zone design, upper zone holds two optical drives, one floppy drive and four HDDs. the lower zone holds the motherboard, power supply unit and three HDDs. to separate the heat sources for better thermal solution.
• There are three of 120mm blue LED fans at the front to bring the cold air into the system. The fans cover the whole motherboard, and they can remove the heat fast.
• In the upper zone, there is a 120mm exhaust blue LED fan at the rear to draw the hot air out, and improve the air flow inside the chassis.
• In the lower zone, there is a 120mm exhaust blue LED fan at the rear to draw the hot air out, and improve the air flow inside the chassis.
• There is a openings on the motheboard tray to allow user removed the CPU cooler.
• There are vents on the PCI slots, provids extra cooling to graphics card.
• The power supply unit is at the bottom of the case. It can draw in cold air directly through the vent below the power supply unit. This cooler, fresh air will keep your PSU components more cool and stable and thus extend the PSU life-cycle.
• The PC-X900 supports liquid cooling system, the two holes at the rear of the case allows water tubes to pass through, and the rubber cover can protect the tubes away from cutting.
• On the back of case has fitted a fan controller, user can adjust the fan speed to get the best balance between silence and cooling.

User Friendly Design

• There is a PCI Bracket allow user to connect USB3.0 cable from I/O port to Motherboard.
• All new tool-less design from Lian Li aluminum chassis. To do this required a great many innovative patents to be filed worldwide. The ideas will make installing and maintenance much easier. For example when installing the 5.25” optical drive, just slide the drive into the 5.25” bay, and close the mounting bar to secure the optical drive, as simple as that.
• There is a modular HDD cage, simple un-do the thumb screw, and silde the HDD cage out, mount the HDD with anti-vibration kit.
• To install PCI add-on cards require no tools at all. Simply open the aluminum arm of the tool-less PCI add-on card holder, insert the add-on card to the motherboard slots, and close the aluminum arm to hold the add-on card in position. The additional rubber padding on the aluminum arm assists in gripping the card bracket and securing it firmly.
• To release the solid side panel, simple just un-do the thrumb screw, and pull the latch. There is a hook for security lock.
• There are openings on the panel between different layers, Lian Li has fitted a protection kit to avoid sharp edge damage user's hand or cut the wires.
