The Lian Li PC-D666 [System 1] has eight expansion slots, so there is plenty of room for extra components, which may be a deciding factor when planning on the longevity and build type of a PC system. The case has five 5.25" drive bays, which is more than enough to house various drives, particularly optical drives. With six 3.5" drive bays there is also plenty of extra HDD space as well. You can even slot in an SSD or a laptop drive in one of the six specifically designed 2.5" drive bays

Made primarily of Aluminium, the Lian Li PC-D666 [System 1] is built to be strong, lightweight, and well-ventilated. This often comes at a price premium, but some see the benefits to be completely worth it. Whatever your case's material, it is important to keep a consistent airflow so that heat doesn't build up inside. It is therefore advised that you make use of the available built-in case fans and fan installation sections.
