To expand on the stellar part slightly, if the proposed cluster is to be powered on all the time, but won't be in use all the time, it's worth noting that the C7 has very low power modes which are still running, albeit very slowly. This would make such a cluster quite responsive in terms of starting jobs from the "just sitting around" state, without requiring any of the complications, overhead, and longish delays associated with returning from sleep modes. In theory the kernel should handle this power conservation for you automatically if the cpufreq modules are installed and configured properly. The power consumption when the system is sitting around would be minimal, probably just a few watts. This assumes that the board in question actually supports these low power modes. This is probably NOT a safe assumption for an el cheopo board.
