There is a 4.5 gig .dmg that works fine.
I have found a sparsed.dmg for install of Leopard. It is only 4.5 Gig and is fairly easy to install. I have had it running now for a couple of weeks updated to 10.5.1 and its great even a little faster than Tiger I think.
Contact for the torrent link its still alive and all the instructions are there as well. :cool:
