Building new computer and need confirmation everything works together

I am building a new computer for some low end gaming and other menial functions. I have done a moderate amount of research and have come up with a build that i believe will be a good fit for what i need. My main concern is that, although i have check all the components, some of them may not work together. I would appreciate it if anyone with more knowledge of the components would be able to confirm that they will work together. This is my first time building my own system so any suggestions would be appreciated, although i would not like to deviate very far from the build.

More about building computer confirmation works
  1. The cm power supply is poor quality. Ideal for holding a door closed but not real good in a computer .
    Instead look for an 80 + bronze rated unit

    If your copy of windows is an oem version and you have used it in a previous computer you wont be able to re-use it anyway .

    Generally speaking Gigabyte and ASUS make and sell much better motherboards than intel . Look for one of those with an H77 chipset instead
  2. My copy of windows is unused, so that will not be an issue. I will look into a higher rated power supply and a different motherboard.
