Each build is different. That's where you motherboard manual comes in handy. It'll take you step by step in assembling most of your hardware.
You might save yourself some time and aggravation, if you connect your CPU/HSF, PSU, and power switch before mounting your motherboard in the case. Try to power on with just those items, and see if the system POSTs (you should hear the normal system beep). If you do, continue adding hardware.
