The Phanteks line with built in RGB seems to be right up your alley. While many have copied the Tempered Glass designs , Phanteks was the first and still the best option to my eyes. But the RGB and Tempered Glass is going to come out higher than your budget allows.
The Entoo Pro M has tempered glass but not the LED features found in higher priced cases. The 400 Series is not available in many european countries. The Enthoo Luxe TG and Evolv TG are the cases most desired but again, availability in Europe is either not there or in the €160+ range
