Check the sides of the radiator where the tanks and the tubes meet. It's kind of hard to see. Mine only leaked when it was hot, so I wasn't getting a puddle, just steam escaping. If you have coolant, you should be able to smell it when it's hot. Check your hoses for pinhole leaks or bad clamps, especially the bypass hoses by the water pump, they're a pain to change. Here too, you might only get a leak when it's hot. If you have a leak you should see evidence of the leak, not necessarily water coming out, but water/coolant residue.

Once you find the leak, you should flush your system, since your coolant is probably no good even though it still looks OK. Something to do with leaks causing the coolant to get super hot at the leak site and burning off the protective chemicals.
