I am Not a Geek dot com has posted a review on Rheobus

The Rheobus is another creation by PCMods, Bigfoot Computers has sent it to us for review. Unlike most bay buses or fan buses or whatever you want to call them this one doesn´t just use a switch. The fans each a have a dimmer knob. As you can probably tell my looking at the front of the unit you can hook up to four fans to it.

Then fans can not be turned off completely, but they can be turned very low. When the dimmer was turned all the way down I could not hear any of the fans. When the dimmer is turned all the way up, that is just like if you had plugged them in normally. The blue LED´s in the front also get brighter or dimmer as you turn the know.
