>(in terms of power requirement) You can buy a single off the shelf Proliant microserver which is the size of a shoebox, put Vmware on there (or your virtuaization product of choice) and have god knows how many VM's running with a very modest power load that will blow away any sort of jerry-rigged Pi's shoved into a 1U solution. And be reliable and have raid and have ecc memory. Hardware is kinda a solved problem now. Shame the pi isn't more powerful. I was looking at deploying Freepbx in my home and the performance of the web interace of the Pi is terrible. I'm not sure what people actually use them for. I'm probably going to just get a beaglebone that's 2-3x as powerful for a measly $15 more.
