I know many of you will say that building is much better than buying. I would agree. However I don't have a lot of money, my dad doesn't want to spend several hundred just to screw it up in the building stage, I am inexperienced, and I don't plan on playing super taxing games. My budget is $500 but i can go over if its really sweet. So, tips on how to prove there is no risk in building my own to my dad or suggestions on a good quality prebuilt for $600 or less. The games I plan to play are: Gmod, Minecraft, CoD: AW, CS, Arma 2/DayZ.
