Lian-Li Lancool PC-K63 cont.Only two of the three 5.25" bays feature a tool-less design and it's a rather poor implementation compared to the version used by Cooler Master's Enforcer. Meanwhile, the 3.5" hard drive bays don't have a quick-mount system, instead using four special noise-dampening screws per installed drive.
In total, the PC-K63 supports three 5.25" devices, six 3.5" drives and two 2.5" drives. There are two removable drive cages and each support three 3.5" devices and one 2.5" device. The cages mount sideways, allowing you to install hard drives with data and power cables facing the door.
There are also eight expansion slots, seven of which feature a simple tool-free mechanism.
The PC-K63 comes with five fans, including three with blue LEDs: two front-mounted 140mm LED fans, a single rear 120mm LED unit, and two 140mm top-mounted fans. Each has its own 3-pin to 4-pin adapter for greater flexibility. This is a very nice setup given the relatively affordable price tag.
The Lancool PC-K63 can accommodate a wide range of hardware, including 285mm-long graphics cards, giving the 270mm Radeon HD 6970 and GeForce GTX 580 some breathing space. You can extend that to a gracious 415mm by removing a drive cage, in the event that you have an HD 6990.
CPU heatsink clearance is 175mm, which is the same as the Enforcer and means even the tallest heatsinks will fit comfortably inside the PC-K63.
Lian-Li has included a tool-less PSU holder that locks the power supply into place. This adds extra stability for larger units, but you'll still have to mount your power supply in the traditional fashion with four screws at the rear.
Although there are some details that could be improved, the PC-K63 is a solid case inside and out.
