Feature - High Quality Craftmanship
Minimalism style, with 3mm thick alumium extrusion front panel with hair-line brushing and anodized finishing, vent holes covered with painted steel mesh.

PC-A20 has modularized hardware design, the HDD cages, can be remove, or modify to suit user's need.

PC-A20 also features multi-heat zone design, ensure the best thermal & silent solution.

The power and reset button has blue LED backlighted feature.

Silent Performace
To keep the system cool, and also running silent at the same time. PC-A20 using large sizes fans which running in low RPM, but still have enough air flow.

There is a three-speed fan controller in the front, user can use it to adjust the fan speed to suit their needs.140mm fan speed 800-980-1180 RPM; 12mm fan speed 1020-1240-1500RPM; Factory set to mid speed. user can adjust to get the best balance between silent and cooling.

There are anti-vibration spring fited inthe 5.25" rack to reduce the noise which cause by the vibration.

Lian Li patented anti-vibration HDD mounting design, it is easy to use, simple use the thumb screws to secure the rubber ring to the HDD, and slide the HDD to the special made HDD cage, and the rubber ring will absorb the vibration and reduce the noise.

There are anti-vibration kits on the chassis to reduce the vibration noise.

The fan also mounted with rubber ring to reduce the vibration noise.

The rubber strip on the front door panel, it stop the door to knock the front panel, to avoid the door scratch the front panel, also close the gap of the door and front panel.

PC-A20 has fitted a 120mm fan on the graphics card holder to cool the memory and north bridge chip set. Fan speed can be adjust by the three-speed fan controller,factory setting to middle (1240RPM), user can adjust the fan speed to suit.

Power supply unit located at the lower part of the chassis, and it can get the cool air from the bottom of the chassis. Ideal for keep power supply in lower temperature to keep in best output performance, also keep the components cold to extend the life cycle.

There is a panel between HDD and PSU sections, there is space for a 120mm fan for improve air flow.

There are opening for water tubes on rear of the top cover. Ideal for user who would like to fit liquid cooling system into PC-A20.

User Friendly
