transitionality, completely no-go, sorry. You can continue using Xp which is, i bet, working great on that machine. I personally like those 'aged' machines, i could never sell any of mine. I turned a few into servers and used them for varios things.

Yours is not that old and i think it will still do its job. If you maybe in the future decide to assemble a new machine you can build a cheap one for Mac OS X.
