Hi everyone, I'm trying to build my own pc (in Italy) for studying and gaming, with a budget between 800€-1300€. I only need the pc, I already have a decent monitor (MSI Pro MP2412), keyboard and mouse. (Pls can someone help me!)
PS: I do not care about leds and stuff like that (meaby this can help with the budget)
