I've understood that since Apple came out with the G4/500's, they've made some changes to the motherboard design, hence it being called "Rev. B." Anyone know what those changes may be? Apparently causes some problems with some PCI cards. Also, how can a user easily find out if they have a Rev. B 450 or 400?

There are a number of visible changes, probably the easiest is to check the AirPort antenna cable: in Rev. A it goes up to the handle, in Rev. B it goes behind the side door.

On a related note, my Rev. A shipped with an ATI Rage Pro graphics adapter with a mini fan, my Rev. B without.

Just to throw this in since you's guys are talikin Sawtooth: Been up and running now since I got it. (ordered day 1) It's the only Mac I've ever had (out of 9) that has never crashed. Amazing!
