Does anyone know where to get the plastic fan ducts like on mnpctech.com, except not from them? I know that they don't make them as I have seen them at performance pc's for a little more. I just wanted to know if anyone knows who makes them so I could get them at OEM prices or ideally buy them locally. I don't have to use that style, I just need some. I know that I could just get some 4" pvc, but I don't feel like shelling out $16 for like 14 feet of it when I only need 3". I know that $4 isn't a lot of money, but I kind of need a lot of them, and they kind of add up fast.
