I agree, this is a dreadful idea. The CPUs are going to hog a whole load of energy (as are the motherboards). The HDDs are going to be seriously used and probably prone to complete breakdown.
An ARM SoC would do this same job much faster probably at much less cost, with FAR less energy consumption.
