The pc rack has 4 fans during the roof but features a dispersion cover over that. The only thing I can Feel to do now is, eliminate the dispersion top and come up with a funnel to deal with the admirers and connect on to the duct, but This is able to suggest a length of about 3.5m of 125mm duct through the RM1/two wall.
