I too had never built a pc before. The guys here talked me into building, and they helped me out alot.
I am very glad I listened to them and built it myself....I got so much more for my money.
I am not sure about that Ram, you may be able to get some crucial ram, or corsair, for not much more. If you get an Asus motherboard, they seem to recommend corsair ram, although that is not necessary.
I really would not get an open box motherboard, because the you may be forced to buy all the extra cables you need...you should be able to find a good deal on a new and completely boxed motherboard.
You are gonna be very happy with your new pc..... I hope you enjoy building it and enjoy Crysis.
you picked a pretty high resolution monitor, so be aware that you may need to upgrade video cards more often than if you would have picked a lower resolution monitor. If you plan on running 2 video cards , then it will not matter.
That is gonna be a nice pc.
It's 50 more dollars to get one that isn't open box.
I don't know how to build a PC so I have no clue about cables, or anything like that.
I'm probably just going to google some sort of guide on how to build a PC.
