thanks for the info on possible upgrades. just installed a 100 gig HD and now will be upgrading ram and adding second HD when more funds permit. another question. my sawtooth connects great if its plugged directly into my cable modem but will not connect via ethernet thru my wireless belkin router, but it pings and the G4 says in the network status that it is connected. im using OSX.3 what am I doing wrong? why wont any pages load? thanks in advance TmB
