Rev. B
Here's a thought: while it's great to have the newest version of anything, I have to wonder if it isn't a bad idea. When I bought my G4/400 a few years back, as luck would have, I ended up with Rev. B, and avoided the numerous problems reported in Rev. A. I'm upgrading the CPU of the G4/400 to 1.25 and waiting for Rev. B.
