I adjusted it anyway to something i would go for,

it's just to show how you can choose differently since i don't know where you live and how it is with parts there.
Things different are,
case=cheaper and a nice one i think
psu=just more powerfull
motherboard=possibility for overclocking
ram=2x2gb=dualchannel
