Lian Li's new PC-O12 is an interesting case.  It bears many similarities to cases currently on the market, with tempered glass windows, cable management features and a separated chamber at the bottom which holds the PSU and drive cages. 

The way it differs is obvious when you look at the back panel and alignment of the four expansion slots for graphics cards.  They are designed to allow you to mount your GPUs vertically with the use of a 440mm PCI-E 16X Riser cable.  This will let you show off the artwork and LEDs on your card and is touted as increasing cooling efficiency.  While this will give you a unique looking system it also adds an impressive price tag of $399.99.

Tempered glass adds a touch of class
The PC-O12’s flawless tempered glass front and side panels make it a sleek and sophisticated showcase for the latest cutting edge computing technologies. Tempered glass is tough, safe and very durable, providing a ‘fresh from the showroom’ appearance indefinitely. The PC-O12’s alluring black aluminum outer body and panels complete the picture. Internally, a rigid steel frame provides a firm foundation for state of the art features.

Ideal balance of chassis size and features
Despite it’s space-saving format, this mid-tower enclosure offers plenty of room for the most powerful hardware. The 440mm full bandwidth PCI Express 16x riser cable allows flexible vertical graphics card mounting to enhance cooling and to show off the latest graphics technology through the tempered glass side panel. The roomy case interior fits graphics cards up to 340mm long and CPU coolers up to 75mm high.

A case with great low-noise cooling performance
With up to five large-format fans, this chassis ensures valuable PC components keep running cool, prolonging life, enhancing performance and reducing noise. There’s space for three 120mm fans at the top of the case, plus two 140mm or 120mm fans at the front. With so many airflow options, users are able to reduce fan speed and reduce noise.
