He's probably looking at spending $200 for both the case and CPU cooler. We usually buy off Amazon, New Egg or Best Buy. He is trying take advantage of Black Friday sales.
My brother bought all of these parts except for the case and CPU cooler. Does this look like a sufficient enough cooler and case or are there better options. He is going for a budget build.

I currently have 4GB of RAM (2 x 2GB) and want to add 4 more. Is it better to add two more 2GB sticks or should I replace my current 2 x 2GB sticks with 2 x 4GB sticks
