[Build Help] Is this a solid build?

http://pcpartpicker.com/p/qtDm

• I'm new to PC building; does this contain everything I need to get a PC from parts in the mail to on the internet? CD drives, USB drives, everything?
• Could I change the case? I don't like this black square one (someone helped me with this build and chose that one). Which cases are compatible?
• Could I upgrade to a GTX 680 instead of a GTX 670?
• Is my power supply large enough?
• Could someone help me edit this build? I need two USB slots on the front; it appears I only have a CD drive.

Thank you.
