What to do with an old PowerPC Mac?

So I moved a few month’s ago and I’ve been trying to dig myself out of the mountain of unpacked boxes, while trying to put my computer’s back together I found my old 1.25GHz PPC MacMini. I had put Fedora 10 PPC on it before I moved but found 3rd Party Linux software lacking. I put Mac OS X 10.5 back on it but now I still don’t know what to do with it. Any Ideas?
