One last thing: Are you sure that the processor and graphics card are the best? And how much RAM does it have? Btw I added this case :3 http://uk.pcpartpicker.com/p/1uVkj
That processor is the best in the price range, and same with the graphics card, however for an extra 60 euro's you can upgrade to one that's about 30/40% better (Nvidia) but it will push you over budget
