The look of PC-9F is in minimalism style; users can access the front I/O ports easily. The front panel design is a combination of art and functionality, with the hair line brushed and anodized aluminum touched up this outstanding high-end chassis. The PC-9F carries Lian Li's high standard of quality requirement. All the sharp edges have been removed for user's safety. In addition, the external and internal surfaces have hair-line brush anodized aluminum in keeping with Lian Li's classical style.
The internal layout has the motherboard on top of the power supply unit, which allows for easier access to the motherboard as well as more room above, thus larger CPU coolers can be used. The power supply unit at the button of the case is cooled with fresh cool air directly from the outside of the case, instead of pre-heated air from within. This will bring down the core temperatures and extend the lifespan of the PSU significantly. The PC-9F is a mid-tower case, which is ideal for the graphics cards in combination with the best thermal dynamics. All the internal installation can be done without tools, and is easily adjustable to optimize your hardware setup. Especially in the advent of adding in graphics cards, equipped with 8 PCI slots, can hold three or more graphics cards. The hardware installation with PC-9F is very easy and simple. The front panel is detachable and they can be removed without tools.
Lian Li uses the "Made in Taiwan" high quality aluminum panel for all Lian Li chassis. The solid main chassis was folded with aluminum sheeting to make a more sturdy structure which has less vibration. The removable front panel is joined with specialized plastic kits that prevent the metal parts from touching each other, ultimately reducing noise created by fans and HDD vibration. The 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 power supply has rubber pads for both insulation and support. Also secure the PSU without scratching the painted surface.
The PC-9F is equipped with large cooling fans, with low RPM, which still provide enough air flow to cool down the hardware adequately. The rear exhaust fan just next to the CPU, it can remove the hot air out fast and silently. There are vents on the PCI slots, provides 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 lifecycle. PC-9F 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. There is a special quadrate opening of motherboard tray, user can easily switch the CPU's radiator without remove motherboard.
The dual design is for better compatibility options. All I/O ports on the top cover, allow for easy access, there is also a dust-free cover to protect these connectors. All tool-less design from Lian Li aluminum chassis. To do this required a great many patents to be filed worldwide. The ideas will make installing and maintenance much easier. There is a modular HDD cage, and silde the HDD cage out, mount the HDD with anti-vibration kit. There is a patented cable management clamp for cables to pass through, allow user convenient manage the cables. Aluminum motherboard thumb screw, user can easily screwed motherboard without tools. There are openings on the panel, allow user to manage the cables. There is an air filter at the base of the case to stop dust from entering the case. The filter is washable. The vents are specially designed to retard heat and fire crossover should a short circuit cause sparks and excessive heat within your system. This feature is designed to prevent the problem from spreading outside your case should the unlikely event occur with your components. No tool required, simply secure the anti-vibration rubber ring to the HDD. There is a fan hole on the top, user can easily remove the screws, put an intake fan on it for better thermal performance.
