Trying to Fit a Core i5 into a $400 Budget

Hi everyone. I was looking for parts to start my first-ever build when I saw a bundle deal on Micro Center (http://) for a Core i5-3570k w/ a decent-looking motherboard for ~$200. I'd like to know if the other parts are right to accommodate this combo, or just general advice/ improvements.

Purpose: Programming in Ubuntu, games (will add a graphics card when I can afford it)

Budget: ~$400

Overclocking: No (I realize that this CPU is meant for OCing, but I really don't need to and the price beats the locked versions.)

Monitor Res: 1080p

OS: Ubuntu 12.04

Purchase Date: This weekend

Part List (minus CPU + Motherboard):

I really don't need this kind of power now, but I feel like the price is just too good, and it's my dream CPU. I greatly appreciate any input from those more knowledgeable than I.
