My $1k build

I'm building my first computer and I need some help choosing parts. If anyone could give me some feedback on my choices that would be great. I'm trying to keep this build in the $1000 range with monitor and operating system, and peripherals included. If anyone could give me some parts that would help cut costs that would be great. All the parts I have chosen are from newegg.com

Also, if I could save money buy purchasing a cheaper case that would be great. Newegg had a good deal with the Antec combo so I opted for that but if you have any cheaper alternatives that would be better.
