I am posting from my PowerMac G4 MDD 1.5 Ghz (OC) with 1.25GB RAM and a 64mb radeon 9k running Leopard. I sold my windoze workstation and all this needs is a working DVD drive to be complete, and a few minor things: Internal Speaker kit needs replacement, want a dual cpu card I can OC to 1.67 and a copper heatsink w/ cooling tube. I also want to eventually ditch my clicky keyboard and get a mac keyboard and maybe bluetooth.
When 2.5 comes out, I'll DL it and install it on a second HDD, shrink my current HD partition and add a sharing partition.
