I'm not new in this but i would like to know i have 2500 euros and i want to invest in rig, i want to mine ETH. Can you tell me what to buy and how much i can expect per month? I know maybe 2500 euros (almost 3000$) is not too much but i would like to see suggestions and think to buy.
Since you have already your target coin to mine,I would suggest to read about miners that is mining ETH see below threads
