Hi,
I made something for 1580Eur. (aprox. $2100). Due to pretty expensive parts like the CPU, GPU and the Monitor, there is no budget left for: Mouse, Keyboard and OS. Maybe you should cut on some hardware.
All the parts are form Germany, since Italy is close to Germany the shipping will be fast and inexpensive. If you don't like shipping form Germany, use this build as an example and search the same parts in Italy, the prices for PC parts are almost identical in all EU Countries.
Ciao
