You wouldn't save any money buying piece by piece. It would be best to buy all at once. Newegg is very similar to ZZF in pricing when shipping is included. I have never used ZZF (and that's why I'm partial to Newegg) but they have an excellent reputation. I find the ZZF website to be very confusing, however.
