The black PC-Q35B Mini Tower Desktop Case from Lian Li features a lockable front door to help prevent access to the power button as well as the optical drives. The door also helps reduce the amount of noise generated from the system. Behind the front door, you can install up to two 5.25" drives with the hard drive cage installed or remove the cage to mount up to five 5.25" drives. The unique hard drive cage holds the included 120mm fan as well as up to four optional 3.5" drives and two 2.5" drives. You can attach a fifth 3.5" drive to the bottom of the case. This case is designed to support motherboards in the size of mini-ITX and mini-DTX.
Lian Li has designed this case to draw cool air from the front and expel hot air through the included 120mm top fan. To help prevent dust, there are two removable, washable air filters on the bottom of the case. This case supports a separately sold liquid cooling kit that can be installed by removing the top fan.
The bottom right side of the case comes with two USB 3.0 ports along with one headphone jack and one microphone jack. For PCI card support, it has two expansion slots and can support graphics cards up to 11.8" long. Once an ATX power supply is installed, you have enough room to attach a CPU cooler up to 3.7" high.
