Yea the cost savings can go towards a proper 12v deep cycle battery. Currently the two schools in Lesotho are using MSI Nettop as school servers. In the context of charging 30-100 XOs, the additional power consumed by the school server is negligible. However, at the second school which charges the laptops using individual solar panels, the school server takes a dedicated solar panel charging a pair of car batteries. The big surprise was that the MSI does not boot on 12vdc. This required adding an inverter (designed to charge laptops from a car battery). Good to know, thanks. I was hoping the Trim-Slice H would be suitable. I am concerned with its fixed 1GB memory. The Utilite looked like a promising alternative, but supports only SSD. We may have to wait for nettops based on the new Atom technology for a one-box solution. In the meantime, the current Atom based systems are doable in an off-grid deployment. By the way, the need for the school server is closer to 50 hours per week than 24/7. Normally it needs to be booted only during the hours when children are in school. Valid point, that should be taken into account when calculating total power requirements.

Perhaps another avenue to explore could be SSHD's (a hybrid of SSDs and HDD's). They would cost significantly less than an SSD (a 500GB SSHD retails $80), yet meager on power consumption about 2.5-3W better than an HDD, 1-1.5W worse than an SSD.
