24 hours after its launching, I tried to find ISO file at mininova.org and sadly only got 1 seeder. Then in Sunday night (GMT+7) I found that there are already hunders of seeder providing the latest Mac OS X 10.5. The file size is 6.56GB, fit into 2 DVD Single Layer. You need Nero or other burning tool to burn the ISO Image into DVD Disc.
Since my connection is just cable with 384kbps, I just can wait until
torrent seeder reaches thousands before start downloading.
