A computer without a system bus?

[prim07]

I was looking at buying a new computer, however the one I was most interested mentioned it had no system bus.

Could this be a mistake on the website, or are there computers w/o a system bus? (Not 100% sure what system bus is exactly)

That's the link to the computer I'm talking about. If you scroll down and click on specifications, you'll see what I'm talking about.

Thanks for any insight!

All I know is that it carries data between the CPU and the Northbridge, which is connected to your graphics card and RAM. So, honestly I'm really not sure how a computer could not have one...
