I think your missing the point of what other members are trying to tell you.
The orignal Computer you posted isn't that great and don't expect that to play many Newer games on Medium to Max Settings.
You will be building this computer yourself, not buying a prebuilt.
The Parts suggested by 003 Is a great start (Im not saying needacpu's suggestion was bad either). You can order parts off many websites. As for building the computer you can find many guides to assite you in the process, and you can even ask here.
