I'm sorry, but... cobra doesn't really give you a good critique at ALL. I'll edit this with mine in a moment - I just don't want you to hit the buy button thinking it's great, as there are a WHOLE lot of things you absolutely should change.
Alright... so:
1) Don't buy an i7. The only difference between it and an i5 is slightly more l3 cashe, and hyperthreading. The l3 cashe is negligible and doesn't matter for games anyways, so we'll focus on the hyperthreading. I'm going to change my usual argument here (which is that hyperthreading is not only useless, but the games that claim to use it are actually slowed down by it), because hyperthreading has come to represent a slight boost in a few games... but it's really not worth paying $100 for 3-5 more FPS in a half-dozen games that you might or might not play.
Buy an i5-3570k, add $100 to the counter of what I'm going to save you.
As for Haswell, I will still recommend Ivy Bridge if you plan on overclocking, because it's much easier and more reliable to get a good overclock on Ivy... and haswell is only about 5-10% faster, clock-for-clock. (And if you get a way worse overclock, which can happen pretty easily...)
2) Ditch the liquid cooler and run as fast as you can. If you're going to go with water cooling, do it right. Closed-loop water coolers use subpar parts to cut costs, which means the pump is much more apt to fail than a real one would. On top of that, when compared to an air cooler of equal price, the air cooler is going to be cooler, quieter, and WAY more reliable... so just get a $30 Hyper 212 EVO or a more expensive, 140mm cooler and don't take risks for no reward.
3) I wouldn't buy that motherboard. Something like the AsRock z77 Extreme 4 or Asus p8x77-v LE or LK are going to be $60 cheaper and perform exactly the same and be just as reliable. It's up to you, but you don't need the extra ports and options of the pro model, so why pay for them?
4) Don't bother with such expensive memory - that's a hideous waste of time. You're honestly not going to see a real-world difference between that and a set of DDR3-1600 MHz RAM with a Cas of 7. (You can usually overclock most standard Cas 9 ram to have a lower latency like that.) Why pay an extra $80 for, in the best scenario, 3 fps?
5) Bad pick on the SSD. Buy a 120GB Samsung 840 EVO for $110 - it's newer and faster. If you really wanted, you could get a 840 pro or OCZ Vector to get the best performance out there... but it won't be noticeable over the EVO.
6) Horrible, HORRIBLE pick on the graphics card, sorry. As soon as the 670 came out, the 680 failed - The 680 was only 5% faster than the 670, but it cost 25% more. Now, it's even worse of an option - you're paying $500 for a card that is quite easily beaten by the $400 770 and absolutely smashed by the $650 780. (*I would take the oodles of money I'm saving you and upgrade to that 780... or else even better, upgrade to a 120 Hz monitor [Go with BenQ], a mechanical keyboard, and a good mouse. You'll appreciate it.)
7) Really? $180 for a full tower case? Spend $100 on a decent mid tower case that will be just as well built - not only will your wallet thank you, but so will your back as soon as you have to move your computer at all.
8) You don't need nearly that much power supply. With a 700 series card, a 550w power supply is more than enough. If you go with a 670 or decide to stick with a 680, buy a 650w power supply. (*I suggest the SeaSonic X-650, which is pretty much the best power supply ever made.)
9) Oh give me a break. Why in the world do you think you need windows 8 professional? You're paying a WHOLE lot more money for the following: Domain-Joining & Group Policy so you can manage computers with Windows Server on them. A Remote Desktop Server, which is just microsoft's version of free, open source programs. BitLocker, which is good so long as your hard drive doesn't get corrupted. Hyper-V, so you can run virtual machines. And virtual hard disk booting. Those last two are the only useful ones, but you probably don't use virtual machines anyways.
So. In all honestly, this build looks like something put together a year ago by someone who has way too much money and just wants a computer that seems impressive and gives them bragging rights. Bragging rights aren't worth $200.
Make changes, and you'll have a FASTER computer that's cheaper ... and you'll be able to have an incredible monitor and keyboard setup, which in all honestly, will be more impressive to the non-tech-savvy than that the computer itself will be.
