I am seeking help on a couple of things...

Firstly - fan controllers: I want something which will handle up to 6 fans - 2 of which will be CPU and GPU. The rest will be case fans. I may yet want to add more fans later - the case has provision for 8 fans. I have never used anything but a single fan controller before which came with an aftermarket GPU cooler so this is kinda new territory.
Had a quick look and kinda liking this style of controller:
Do other brands of controllers come with cables as well?

A while ago I was given a heap of LED fans which I intend to use with the above case and the controller which I intend to buy. I have never had an LED fan before so am not sure what of voltages, cables to connect them etc. I am assuming I can connect all LED fan connections (8 for the case potentially and 2 for the GPU/CPU) in series to one molex connector?? Is there a cable to do this or do I need to get something made? I am hoping there is some kind of kitset one can buy for this?
The fans have a 3-pin fem connector for the fan power, and 2-pin male connectors for the LED's

It will be cabled in series, but they are actually wired in parallel.

The molex connector carries negative, and +5v and +12v
The fan will have the same connector, but be wired to the pins with the voltage it wants, so you should be able to plug it in and it will go. Some fans are 5v, and others are 12v.

Fans use very little power - led's even less. I would not be surprised if 8 fans used the same amount of power as one hard drive.

I am not an expert on building fancy cases, but i believe you can get cases with a high output power supply and a fan controller built into the case itself. Alternatively you can also get fan controllers that sit in the secondary CD-ROM or floppy bay.
