The case should have come with cables with which to connect the front panel to your motherboard. There will be one to connect the front panel USB ports as well. No doubt you have some of the front panel connected or the power button wouldn't work.
You can plug them into either of the 9 pin USB connectors to the right of your PCI ports. Immediately to the left of your SATA 1 and 2 ports.
As for the case fans you can connect them with molex cables which should be included with your PSU, or to any of the 3-4 pin CHA Fan ports on your mobo. There is one directly below your mobo's 24 pin power connector.
Ah, your front panel ports are USB 3.0. Unfortunately your motherboard doesn't have the onboard USB 3.0 header to wire up your front panel ports. You only option would be to get an adapter and plug them into either of the 2 USB 3.0 ports on the back panel (I would route the cable through one of the rubber grommets for water cooling).
Its not clean but its the only way for boards that were released with USB 3.0 but before the onboard header. I have the same problem with my mobo.
Were you able to wire up the case fans? You should run into no problem there.
