I can get a PC with those exact specs here in the 'States, prebuilt and with that monitor, for about $900-$1150.
I can get that same PC by building it myself, with that monitor, for about $750-$850.
What you paid translates to about $1900.
Granted, you're in Europe, but I really doubt that living there is going to increase the cost by THAT much.
But it IS a good computer, I'll give you that.
