My father has an old powermac (G5 I believe) and wants a modern lightweight OS since apple dropped support a while ago. I proposed Linux and my father seemed intrigued to try it out. Tomorrow I get the machine and get to set it up.

I was thinking of Elementary OS, since he is an Apple fanboy. What do you think about that decision?

Never used or installed it before, but how hard can it be?
*obligatorily mentioning that I use Arch Linux*
