Information on the details for making a new computer


May 6, 2012
Hello, this is my first post, and I was wondering about some information on computers. I am thinking about building my own, and I found a guide that I am following online. I've looked up the individual parts and they all seem to be trustworthy, they're listed as followed:

The basic build that i am using is on the guide, at

The only changes that I am making to the final design is the Case, instead of being what is listed, will be the
Cooler Master HAF 912 Mid Tower ATX Case (RC-912-KKN1)
and the WD Caviar Blue will be 1TB instead of 1 GB.

I am a computer noob, and I haven't ever done anything like this before, so I need to know, is this case alright, will I need a heatsink, or if there's anything I overlooked.

Sorry if this is something i should know, but like i said, I've never done anything like this before. Please help, and thank you in advance.
