Don't waste money on either of those. I can think of at least five cases that are just as good and cheaper or better and the same price (starting with the cheapest: Antec 300 Illusion, Coolermaster 690, Antec 900/902, HAF 922, Coolermaster Cosmos).
I'd go with either the HAF 922 (under half the price of the HAF X, yet almost nothing different) or the Antec 900/902 (the price on those seems to have changed significantly in the last few days, so watch them to see if the price falls).
All you really need in the fan configuration is front fans at the bottom of the case and back fans at the top of the case. That's it.
