u should look into the cool cylinder hood they have a 20inch and a 24 inch witch will fit a 600 and a 400 in the same hood. venting the hood directly is a problem i had with the light rail couse i have a 440crm fan and to keep noise level down i have to use insalated duct witch pulls the hood. i just tried diff setups until i worked it out.
