The Airplex Evo series and the HTF2 series radiators have grills sold seperately for these radiators, so that it looks nice and finished wherever you mount it on your case...
For example the metal plate you see here...
Anyone know any places where you can buy these ? Other than European websites?
(I was thinking about getting two of those for 2 120mm fans from a radiator, and hang the radiator below them and spread out the fans so that i can use 2 seperate grills. Ofcourse make a metal casing around it so the airflow has to go through the radiator to the fans).
