Over-engineered, but interesting.
The screen of the computer that powers the cube and display above the main entrance is pretty ugly.
The screens of the stats computers would be too complicated to be seen from anywhere but up close.
For stats, the best bet IMO would be a feed from a little PC or laptop that was refreshing (even using Flash for a smooth refresh) an output of the live boxscore. You could parse it on the fly using regular expressions similar to the method I used for the ABL stats so that you were only outputting the key stats in a font large enough to read.
My low-tech idea for replays (and I'm not an AV person so it might not even be possible) is to feed the concourse camera (there for every game) through a consumer hard-drive recorder into the screen. Then use the live replay function on that. Those things are $600 tops. The concourse feed is pretty basic (see Dusty's videos for examples) but better than nothing.
And you could easily add to it with a baseline camera -- a steady volunteer with a handycam might even be passable. I've also suggested positioned handycams or an aerial camera mounted in the rafters too.
I understand that the club are interested in doing it properly, but personally, as a fan, I'd rather have something up there than nothing. I'm not expecting NBA-style replays either way.
