Re: $600 Dollar PC Finalized.
You're going to want your motherboard, CPU, and case first. If you can, order those three at once! You'll put your CPU on your motherboard as your first step, the install the motherboard in that case. I know that that case already has a PSU in it so you shouldn't have to worry about that. You'll need RAM, the video card, and the hard drive to get everything else working. Finally, you can get the CD drive, even though you'll have to use that to install Windows. So, basically, it doesn't really matter. But, if you want to go ahead and construct it, go in the manner that I just said.
