Hi Master Captain,
That is similar to how I built my own system.
The things that you have to keep in mind are that,
(1) You have to buy a GUI, (in this case Windows 7), that is extra cost.
(2) You have to buy a hard drive, that is extra cost.
(3) You have to buy a DVD drive, that is extra cost.
(4) You need to know what you are doing when you install or request certain extras.
As I said earlier, the system that Jack is looking at is built with gaming in mind and should cope well with any graphics intensive game. It is reasonably priced as well. I looked on some other sites and for the same spec. computer with an LCD screen the price was huge.
