Lian-Li Industrial Co. Ltd announces the PC-Q21 Mini Tower Chassis for Mini-ITX systems. This compact chassis tucks a full computer into a small box. The slot-load slim ODD bay at the top gives legacy optical drives a cool home or holds a modern SSD. There are two PCI expansion slots and more room under them than in previous models. This lets in more air, and accommodates a very flexible bottom-mounted drive sled. Even the front has space enough for a full 2.5” drive or a 3.5” drive with shorter graphics cards.
