i7 CPUs have been used for all sorts of PC configurations. Your standard library at a university or college, the office worker desktop who does nothing but use web based applications for their job, and so on.

The pricing difference between an i5 and an i7 aren't really that big when you go to Dell and tell them I need 4,000 desktops. DHS isn't paying the same pricing difference as we would be when purchasing a boxed CPU.
