Lian Li introduced a black-white variant of its PC-O5SW case, featuring matte black interiors contrasting white aluminium exteriors, and a large, clear-acrylic window on its side panel. The SFF case has room for a mini-ITX motherboard, with risers wiring out four expansion slots along the plane of the motherboard (ideal for triple-slot graphics cards), a slimline optical drive, three 3.5-inch drive bays through a detachable drive rack, and two 2.5-inch bays behind the motherboard tray, which convert to one 3.5-inch bay.

An SFX PSU is needed to power your rig up. Ventilation includes two 120 mm top exhausts, and a 140 mm right side-panel fan. The case supports graphics cards with 19 cm length with the 3x 3.5-inch HDD rack in place, and up to 31 cm with it removed. PSUs as long as 140 mm are supported, and CPU coolers as tall as 85 mm. Measuring 384 mm x 465 mm x 148 mm (WxHxD), the case weighs 6.4 kg. Front-panel connectivity includes two USB 3.0 ports (standard header), and HDA jacks. The PCIe riser supports PCIe gen 3.0 standard.
