What do you think about this desktop? I don't think I'm going to overclock it, so I should have taken the i5 2400 and my budget was pretty limited(around 600$, but I wanted a case a little bit fancier that the cheapest one =p)
My brother already ordered it yesterday night, because he was getting impatient, but I didn't really have the time to check each components(I was thinking a phenom and a better graphic card might be better for gaming), but if there's a really better alternative, I can simply cancel his order.

PS: This desktop is mainly use for casual gaming and regular use

Thanks
