Acrylic case made from parts at Home Depot for about $30, powered by the existing inline duct fan from Amazon for $70. It's connected to the dryer vent in my apartment and heat in the room is very low. I bought one acrylic sheet for $25(cut into 4 pieces), 8 corner braces $3, and sixteen 1/2" nuts and bolts for $4. I'm ready for this summer now.
