So we've decided to get some digital signage for our school and have been looking at Navaho and Sedao; both companies that supply 'all-in-one' solutions with cool little boxes that attach to the back of the screen.
We've also been looking at Xibo, and I was wondering, how could someone do a Navaho mediacat style box themselves? Is there any ultrasmall computers out there on the market that would fit on the back of an LCD screen?
