This is my 2nd custom looped build. Im used full os EKWB parts for cooling except the flow indicator, that is Alphacool. The Vector and Velocity duo looks awsome, and keeps the temperarure low. The dual bay reservoir is in the 5,25" slots. The Furious Vardar fans aren't visible, because they are on the exhaust sides of the radiators, and activated, if the temperature is above 50 °C. Im used EKWB 16mm diameter PETG tubes, with white EK fittings. I think the purple fluid looks really fine with black and white colors. I hope you will like it too
