In the past week (mostly) and the previous two months I've been using my PowerBook daily, all it's really needed was a new PRAM battery. Now I notice the hard drive is running noticeably loud and starting to crunch. I'm still running the original 80GB and it seems 11 years is doing it in. When it gets to unbearable I plan on completely redoing my PowerBook as I've been putting it off. New hard drive, msata maybe but most likely a newer 7200 or 5200 drive with some more storage, new thermal paste (arctic silver 5 because I already have it) and a new pram battery. I'm just going to leave the RAM at 1GB as I never really need anymore out of this system.
