Alright after many reviews of Cyberpowerpc (The site I was planning on buying from) I have decided to build the computer with a friend of mine (/cheer). So, if someone will please take a look at these components and tell me what they think, I will be very greatful.
I wouldn't go with Diablotek for the PSU. The PSU I suggested is down to $53 after mail-in rebate now.
Don't get a bad PSU, if that thing's bad, then it could mess up everything else.
I think you could get a cheaper case, like this Xigmatek case.
If you're using AMD, either go with two or four sticks. 2 x 2GB 2 x 4GB 4 x 2GB
Also, this 5450 is only about $23 after mail-in rebate and shipping.
