Managing all the plugs of external hard drives for media server?

First a little background on what I'm ultimately trying to accomplish. I'm thinking about buying a mac mini to use as an iTunes media server and storing archived work files. I would be streaming mostly music and movies (both standard and hi-def). I have an 8-core 2008 mac pro that I could use. But, this seems to be overkill and consumes more power compared to the mini. How much power, I'm not sure?

I like the minis small foot print. I've looked at the mini stacks external drives. I like how they match the look of the mini and seem to take up about the same space as the mini. I figure I might need two to get started. One for the data and one to back it all up.

My main question is what are people doing with all the power supply plugs? The pictures of the mini stacks is some what deceiving. They don't really show that you need to plug in each one to a power supply. So, for now I would have three plugs. But in the future this could grow. This really isn't a big deal. I'm just wondering if there is something you all do to keep the plugs organized. One of the nice things of the mini is how it doesn't need a lot of space, but the amount of plugs needed kinda defeats this a little bit. Maybe I'm just used to the internal hard drive set up the older mac pros allow. Any wisdom on this is appreciated.

I was really just curious what people were doing when it comes to managing all the power cables. I guess the mini stacks might not be the route to go with all the power cords. I could do something like the photo above. That would only have two power cords. And allows for multiple drives. Mostly I was just trying to avoid a mess of cables and wondered if anyone had ideas. Thanks to the ideas so far.
