[Build Ready] Going to build for the first time ever in a few weeks, did i mess anything up? Budget ~€1200

http://i.imgur.com/QEiKh.png I didn't use PCPartPicker because those prices aren't right for where i live anyway (Holland).

I mainly want to play games and do some schoolwork (but i have my laptop for that). I already have a monitor, OS keyboard, mouse etc. Anything i should change or forgot?
