The black Lian Li PC-9N Mid-Tower Desktop Case enables you to build a system with micro-ATX and ATX motherboards and graphics cards up to 16.7" long. It features a tool-less drive mounting design for two of your 5.25" optical drives. It has a standard bay that supports a third 5.25" drive. You can install up to five 2.5" drives or three 3.5" drives along with a single 2.5" drive to the modular HDD rack. This rack can be attached to bottom of the case in different directions, so the drive's connectors can face the sides or the rear of the case.
Cooling the components is accomplished with the two included case fans. The front 140mm fan intakes cool air and the rear 120mm fan exhausts hot air. Multiple fan mounts are available so you can mount optional 120mm or 140mm case fans. This case comes equipped with rubber grommets in the rear to support a sold-separately liquid cooling solution. In addition, Lian Li includes multiple air filters that protect your components from unwanted dust.
The PC-9N offers seven expansion slots for your PCI cards. It is crafted out of aluminum, and a lockable side panel deters theft. On the top of the case, you have two USB ports that are USB 3.0 compatible, as well as a headphone and microphone jack.
