Best Gaming pc under 1000?

This pc needs to be under 1000 dollars and needs to play Minecraft, Sims 3, soon to be sims 4 and other games like that. On Highest or close to highest settings very smoothly and nicely. I rather not build but if its the best thing i'm might just be willing to. Keep in mind i'm willing to go a little over so I can get a nice monitor, mouse ETC. If you can recommend a nice monitor, mouse, Keyboard and speakers that are really good quality but cheap that would be greatly appreciated. Please nobody say don't be cheap because i'm only 13 i'm to young to get a job I'm taking a summer baby sitting job and doing a yard sale for the money so yeah thanks.
