Best of luck. You are in good hands at OCN!
Haha, I'm embarrassed to say I also forgot to plug in my 8-pin connector the first time I built a rig. Needless to say that and the 24-pin are the FIRST I connect from now on
OP take your time, do not set any time constraints, focus and don't be nervous it is quite easy to do and will be a thrill the first time you boot it up.
As others have said make sure you enter the BIOS on first bootup to ensure all your parts are posting properly. Windows 7 I find takes some time to install but you can probably have it together before 12:00am, don't force anything and definitely do not overtighten any screws. The last thing you want is a cracked Motherboard
Otherwise enjoy your build, post us some pictures when you get a chance.
