Looking for comments about this rig, this is my first build.

I already have the case and the monitor. Besides the microATX restriction, I pick the Gigabyte motherboard because of the integrated graphics, the reason why is I can't buy graphics card yet, so take that on mind before recommending any option.
Edit: I plan to use Ubuntu. Mainly to watch movies, play games(Minecraft,TF2,etc).
Edit 2: The motherboard needs to have at least one USB 3.0 header.
