Live in a shoebox apartment with little floor space for a conventional PC tower? Good news: Lian Li has introduced a full line of cases designed to be hung from a wall.
The O Series spans four models and three form factors. The PC-05 is the smallest of the bunch, with support for Mini-ITX motherboards and only one system fan. A second Mini-ITX model, the PC-05S, expands the dimensions slightly to accommodate liquid cooling setups with radiators up to 240 mm. Both Mini-ITX versions are restricted to smaller SFX PSUs.
All the chassis combine aluminum construction with tempered glass faces. They're billed as open-air designs, so there's plenty of ventilation for internal components—and plenty of places for dust to get sucked into the system. If you don't want to mount the cases to a wall, you can prop them up vertically with the included stand or lie them flat on four rubber feet.
To maintain slimmer profiles, the O Series mounts the graphics card parallel to the motherboard via a PCIe ribbon cable. Note that graphics card is singular; there doesn't appear to be a way to add more than one to even the largest member of the family. It may be possible to squeeze low-profile expansion cards into some of the cases, though.
The O Series is slated to be available in February, and prices are predictably steep. The PC-05 is due to ring in at $289, the PC-05S at $319, the PC-06S at $379, and the PC-07S at $419.
