Well, I just finished my first build, so I'm probably not a good one to offer an opinion, but nobody else seems to have replied for hours so let's see if (???) I can help.
My build used a Corsair 400R which has 3 fans, two behind the front grill and one in the back. The one in the back connected to the motherboard Case Fan pins, but the two in the front came out to a standard power supply connector (Molex, you can Google it, 4 pins like you said). My Antec power supply has a whole lot of Molex, SATA, video card and other power connectors coming off the octopus of wires.
As I said, I am a noob so take what I said with a grain of salt.
