What about other architectures? If you don't need x86 compat, perhaps CPU models in other arches have much lower consumption? For a box that runs mainly as router, apache, postfix, cyrus, ... even an old MC68k would do just fine (esp. if you are limited by bandwidth, not CPU cycles...). Perhaps something like Soekris boards could be useful? Has someone used them to build a power-saving server? Anyone living in a country with exorbitant high taxes on power lurking here? -cpghost. -- Cordula's Web. http://www.cordula.ws/
