All of the Sys X versions (Jaguar, Panther, Tiger, etc.) work very will on your G4/400. I would add some RAM if you have less than 512MB. Ideally, 1 GB is nice -- it's not that expensive and very easy to install (unlike some other machines -- iMacs, for example.) Be sure you get quality RAM -- Crucial, for example. Crucial is the retail arm of Micron Technology, where Apple buys some of its RAM. http://www.crucial.com/ earle *
