Notebook-style power supply?

[Smiley]

I'm working on my plans for building a mini-itx system to use as a set-top box, using an old stereo for the case... I saw this case review: http://www.mini-itx.com/reviews/2677R/ and one thing I really like about this case is the external power supply that they have.

Another advantage of having a fanless seperate power adapter is the reduced volume - this sound from this case is much like that from a video recorder whilst it is in standby mode. We like that.

Take a look at the bottom two pictures on the second page. My question is, would it be possible to buy a power supply like this seperately from the case? Or even to make something like this from parts? I don't understand the finer details about power supplies, but I know that this is the type of power supply that I want. I tried following their link to ILAN electronics, who made the adapter they use, but the product info all looks like gibberish to me...

Smiley,
I, too have been poking about the mini-itx site.

If you link over to their store, you'll find this:

The exact same PSU as used in the Cubids. They show it rated at 55W.

I wonder if multiple PSU can be used to build a higher performance system.

For example, can we build a silent system that require 165W if we use 3 of these 55W PSU?
