I am looking to get a 3 1/4" fan controller I only need it for 3 fans, but would be nice if it had a couple of usb ports as well, though that is not necessary, have been able to find a load of 5 1/2" ones.
My criteria are, 1.cheap 2. don't mind knobs and 3. did I mention cheap it can look ugly as s### as it will be behind a door and build quality isn't important
