High end mATX build, does this make sense?

Starting a new build, I've done a lot of research and gone through many iterations of builds and I think I think I've finally come up with a final build.
Does this build make sense, and if so, should I make the front fans intake or exhaust?

MSI GTX 670 PE
Intel i5 3570k
Asus maximus V gene
Silverstone PS07
Antec Khuler 620
Samsung 8GB (2x4GB) ddr3 1600 MV-3V4G3D/US
2x noctua p12 1300rpm (case fans)
1x triebwerk 1200rpm low speed fan (radiator fan)
Western Digital caviar black 640GB (previous build)
Kingston SSDNow v200 64GB (previous build)
Corsair HX620 (previous build)

Thanks for reading and hopefully you have some good suggestions .

Hey, welcome to OCF!

When trying to recommend a build to you, there's some information that's extremely helpful for us to know. If you could answer these few short questions, we'd be happy to help!

• What are you planning to do with this compuer? Please be as specfic as possible.

• What is your budget?
  
  1. Does this include a copy of Windows?
  2. Does this include peripheals (a keyboard, monitor, mouse, speakers, etc.)?
• Are you from the United States or a different country? Are you ordering from your own country or from across borders?
  
  1. Wherever you may be from, does the store that you are planning to order from have a website? It's okay if it isn't in English, we can manage.

• Do you have any specific requests with the build?
  
  1. Do you plan on overclocking? If yes, do you have a specific goal in mind?
  2. Would you prefer the build to be particularly small? - mATX
  3. Would you prefer the build to be particularly quiet?
  4. In general, do you prefer this to be a computer that you can spend money on now and let it rest, or a box built for continuous upgrading?
  5. Do you ever plan on utilizing NVIDIA's SLI or AMD's CrossfireX technologies? These features, with a compatible motherboard, allow a user to link multiple identical graphic cards together for added performance. In real world terms, this lets you buy a second identical graphics card down the line as a relatively cheap and easy way to gain a fairly large boost in performance. However, this requires buying a SLI/CFX compatible motherboard and PSU now, which may result in slightly higher initial cost

Once again, thank you in advance for taking the time to answer these, and I hope you enjoy your stay at OCF!
