I am borrowing a dremel rom work and have already cut out around where my fans are so the air flow would increase. I was thinking of doing a window possibly. I know I wont be able to get the edges perfectly straight and I know That some window kits come with some special molding that holds te window and covers the cut area. Do you think I would be able to pick up the supplies at lowes? I know they have the plexi, but dont know about the molding needed.
