The hub that is included in the package has 6 outputs. All fans can therefore be connected to it. The hub itself, however, also needs a controller. So either a Commander Pro or a Node. The node itself should also be included in this double pack. In summary: It fits!

Mix & match should not be a problem. I would advise against this, however, as different fans are then driven at the same speed, which could make 140 fans unnecessarily loud.
