You didn't mention about audio in your original post. Might you have a gaming headset from your console that can be used on the new PC?
If not, this budget wired headphone is currently on sale @amazon.de
I wouldn’t recommend the Sony golds, the sound is good, but build quality is crap.
Hyper x are good
Steelseries are good, but slightly more expensive if you can stretch.
