Nvidia EcoBook is a DIY Project, based on the Pegatron Cape 7 mini PC using Intel Atom CPU and Nvidia ION chipset with the goal to turn one of these multimedia systems into a book and put it along other books on the shelf. The result is a good-looking and “invisible” multimedia computer system for the living room that you can connect directly to your big HDTV and browse the net, watch HD videos both online and offline and even play games that are not too demanding. In the video you can see a comparison with a commercially available PC – the AOpen MiniPC, but that one uses integrated Intel graphics and a normal mobile Intel CPU instead of a low power and energy efficient Intel Atom processor. Note that the EcoBook PC seems to be using dual-core CPU, but actually that is because of the HyperThreading support resulting in two logical cores seen by the OS and the processor being physically a single core. The recommended Os to install and use with this PC is Windows 7, because of the available GPU acceleration built-in directly in the OS that can take advantage of the GPU performance that the integrated GPU in the Nvidia ION chipset has to offer. The 750GB WesternDigital Blue hard drive is not the typical height of 9.5 millimeters for a mobile HDD, but instead is 12.5 mm, but that is not an issue with this book design as there is enough space and having 750 gigabytes of space in such small size PC is great. The Pegatron Cape 7 has 1GB of integrated RAM, but it is good to add 1 GB more for achieving optimum performance not only for the system, but for the GPU too as the GeForce 9400M-like integrated graphics uses shared system memory for its needs.
