Mini Atx Build Help

Hardware Hub Build a PC
1

      This is my first time creating gaming pc but  do not have a lot of desk space. So i was wondering is it possible to create a powerful Mini Atx build for a first timer? (I also only have a budget of $700)

I will only be playing Video Games I wont be doing video editing.

I would like to play at 1080p if thats possible.

I will be playing games like Metro Last Light, Skyrim, and Farcry 3.

Micro ATX, or Mini ITX?

Also, does the budget include the operating system or peripherals?  What games do you play?

I would go mini ITX if you want to save space. That pretty much locks you to Intel CPUs unless you want to run an APU. 
Exactly what Noob said. What do you need? What do you do on your computer? Gaming, rendering, plotting the downfall of the Government?  What games do you play? What resolutions do you play them at?

I meant Micro Atx.

It does not include operating system or peripherals.

I play games like metro last light, and Skyrim.
