I needed some help deciding on a good case, and was also looking for any comments/suggestions.

I was thinking about this case: http://www.newegg.ca/Product/Product.aspx?Item=N82E16811119137 Comments?

I also need an HDD, was hoping for 300-500 GB, could anyone recommend one?

Also, I'm still very new at this, so I apologize, be patient with me.

Thank you.
