Mac Mini (or other intel mac)

I'm looking for a Mac that will be used only for development (iOS) purposes. I'd be open to an iMac but I figure a used mini is cheaper to ship. It doesn't really matter what the internal specs are except that it has to be an intel chip and not powerpc (did they even make ppc minis?). As long as it can run the developer tools we're good to go. (I assume this just means it needs to be able to run Snow Leopard.)

If you've got an intel mac that's just gathering dust, let me know what you have and what you want for it (shipped to NC).

Thanks!
