Lian Li showed off prototypes of its new breed of cases, which can be used either as flat-bed open-air cases, or as towers. These include the mini-ITX PC-05, the micro-ATX PC-06, and the ATX PC-07. Their design is extremely simple. A tub-shaped metal structure holds key PC components along its tray, while a tempered glass panel tops it off. You can either place the case flat-on, making it an open-air case with its clear-acrylic panel removed, or you can place it along its side, to resemble a tower. The three feature a forward-oriented standard ATX PSU bay, a slimline optical drive bay, two or more 3.5-inch/2.5-inch drive bays, and a PCI-Express 3.0 x16 riser, letting you install a graphics card. Lian Li is seeking feedback that will help it perfect the three. Leave them in the comments.
