Custom rheobus for my specific needs

Hey guys, I'm preparing to do a case mod, and I want to put in a rheobus. Eventually, I'm interested in this DangerDen 12V pump that you can vary with a rheobus, which needs 18W, and the pump will crap out if it has less than 6V. The only thing I've found that'll do that is the vantec nexus nx-201 or something like that, but I don't particularly like the look. Now I've found all these articles referencing DIY kits from PCMods, and one other site which I can't remember, and I've found a few tutorials, but they are all specific and already built. I have a 1st semester undergraduate physics understanding of electronics, so, naturally, I have no idea how to solve this problem on my own. I do know that it isn't too complicated, but that's not gonna put a rheobus in my hand. So, bottom line: I don't really care about mounting, I'm gonna be drilling my case anyway, but I need to know how to build a 4-knob rheobus, with each channel capable of 18W, and resistance varying from 7-12V. I would also like to have 4 LEDs. Thanks a lot.
 
the thermaltak XControl controler http://www.xoxide.com/xcontroller.html has 18 watts per channel (watts=amps * volts) with 4 channels and varies from 7v to 12v. it sells for 13.99 on Xoxide.com

if you think that thats gaudy, the vantec nexus controler http://www.xoxide.com/nexfanconnxb.html (black) or http://www.xoxide.com/nexfanconnx.html (white) also can source 18 watts and only has blue lights. it has 4 channels, and also varies from 7v to 12v. (this would be very easy to paint whatever color.

if you would like help persuing a home built circut, just let me know. otherwise, for simplicitys sake, i would look at the 3 controlers above. trust me, they would save you a lot of greief and frustration, and deff look better in the end
 
Yeah, I've seen those. They would work, yes, but my eventual plan is to fill up 3 of my drive bays with a single piece of aluminum that houses the rheobus and a matrix orbital VFD. I have a pretty specific look I'm going after too, so I think I'm just going to try and build one. I'm definetely not adverse to a little grief and frustration, isn't that what a case mod is all about? I remember that the relationship between watts, volts, and amps is ridiculously simple, but I just don't know how to apply it to buying electronics and building a circuit. If you could give me a quick explanation of how to structure it, and what the parameters for the circuitry have to be, I'd really appreciate it.
