I want to build a computer [my second] and i am looking for ideas. I am willing to spend $2500 on the tower and monitor. [I already have a mouse/keyboard/speakers]. This computer will be used for:

-gaming
-watching movies/listening to music
-web browsing
-writing papers/other school work

it will not be used for overclocking. let me know what you guys can do
