its lego for adults. its too easy for you to screw up. newegg has a VERY extensive guide on how to do it. plus, the parts are not too different anyways so everything hasnt changed much
heres what i would get

heres what i would change out of yours
-i hope you do enough video editing to make the i7 worth it.
-cheap 120mm liquid coolers are a joke. when they blow up (some faulty ones do) they will kill your entire system
-the c70 is a hot house
-WAY better board. cant stress that enough. the extreme4 is built pretty cheaply
-way better fans out there than the sickleflows
-if you want lighting, do it right by using bitfenix LEDs. i find lighting a waste of time though. no one stares at their case
-stick with a 2x8 gb kit for future expansion
-more SSD storage
-evga ftw sucks compared to pretty much every other aftermarket 670.
-1000w is overkill plus the fact that you are using something from coolermaster or rosewell is a sure thing to get a crappy psu
-you change it to windows 7 pro if you want. for your rig, forget it. you can never use more than 16gb of ram since you filled up all the slots
if you cannot PHYSICALLY build the rig (seriously, im 15 and i can do it), you can take all the parts in my partslist, go to us.ncix, fill up the shopping cart, do the price matches to save, and then you can either call or email (calling is slightly better) and ask them to build it for you. they will do a job just as well for 50 bucks. it will take longer since it has to be assembled in vancouver but then its still a hell of a lot cheaper than whatever boutique builders can offer
