The Zotac ZBox is essentially a small form factor PC, designed for your TV. Today Zotac has updated the ZBox with the latest components and features. The third gen ZBox is the largest update to the product line since its inception three years ago.
On the exterior there is a small size increase, a whole 7mm or ~.28 inches, not a very noticeable difference at all. Though there is a very good reason for the slight increase, it's needed to allow room for larger, higher performance parts. The network connectivity has been improved to allow teaming between a pair of RJ45 Gigabit Ethernet ports. If you use the ZOTAC ZBox, now might be a good time to look at upgrading.
The 3rd Generation ZOTAC ZBOX mini-PC takes the NVIDIA ION concept and gives it a serious injection of performance with an Intel Core processor and NVIDIA GeForce graphics technology. A dual-core Intel Core processor and NVIDIA GeForce GT 610 graphics processor join forces to form an unmatched home theater PC combination in the 3rd Generation ZOTAC ZBOX with NVIDIA GeForce GT 610 graphics. The NVIDIA GeForce GT 610 graphics processor enables hardware decode acceleration of popular high-definition video formats, including Blu-ray 3D, outstanding video processing for phenomenal video playback and bitstream audio output capabilities for crystal clear loss-less surround sound.
