OCZ have updated their DIY Gaming Notebook system, first unveiled back in May. Based around a 15.4-inch WXGA+ 1280 x 800 LCD, the new system supports Intel's Centrino 2 platform with the PM45 Chipset and ICH9M for Core 2 Duo and Extreme processors. The original's NVIDIA GeForce 8600M GT video card has been swapped out for an ATI Radeon HD 3650 GPU with 512MB RAM.
