Urgent help needed with building.

[Lythrilux]

So, uh, I'm a noob at building so I looked up a guide on the Internet on putting a pc together.
After finally putting everything together, I tried turning my PC on. The LED light for the power works, the disk drive works too. I'm also sure that the HDD works as I heard some faint noise from it. The problem is, nothing else seems to be working. My mouse and keyboard don't work, they won't connect to the desktop. My monitor doesn't connect to it either, it receives no signal. My headset didn't seem to work either. Generally I think the ports at the back of the case don't work at all. Oh, my fan isn't working either. My processor fan doesn't seem to work as well

Everything is connected with the exception of an IDE cable that I couldn't seem to us anywhere. Can anyone help me with my issue?
