When people think of eco-PCs, the usual things that come to mind are LED lights that are not hazardous materials, hardware, and low power. These are all important aspects of your computer to be more green, but one aspect of computing that is completely looked over the border. There are more than 160 million computers in the United States alone, it is clear that there is much unnecessary metal that goes into computer cases. Well, what can replace metal? Post consumer wood / plastic composite for some time now the site mods and a wooden box full of wooden crates that are popping up, it will save a lot of metal in an important objective. Another idea is that instead of every time you decide to build a new computer, things reuse and recycling of the last of the old part of e-waste equipment. Dell is trying to clean computer case with Studio Hybrid line. But “clean” aspect was not worth price. Dell is offering bamboo sleeve sleeve in this case cost over $ 100. In U. S is a company that is green computer cases, but in Ireland is a company called Iameco where all peripheral devices and computer case is made from biodegradable materials. The only problem is that these computers are certainly not cheap, 999 euros (about $ 1400). But if you help the environment is very important in your life, then one of these computers will be worth buying.
