Something like these would save on power and be as good if not better than an old PC in the same price range
Would they be as quick as a core 2 duo though. Not sure on how reliable those cheap chinese things are. Does it come with a legal COA for windows 8, becuase at that price you have to wonder. Can't see any details on the COA.
