I recently managed to acquire a Bondi Blue G3 iMac for £8, it was bit of a wreck when I got it, barely functioning with OS 9 on it. I've managed to clean it up, stuck 128Mb of RAM in it, replaced the PRAM battery, and upgraded it to OS X 10.3, and its now a functional, perfectly usable machine. It takes 2 minutes to start, which isn't too shabby. However, it does make a lot of noise, which continues when in standby, am I correct in my assumption that this noise is the cooling fan? Is this fan replaceable, i.e. could I quiet it down by replacing the fan with a newer, low noise fan? Odds are, if it were to break, I'd gut it, shove a 15" flat panel in there, and possibly a Mac Mini, but while it's still functional I'd like to make it as usable as possible, and given that it's currently sat in the corner of the lounge it makes a little too much noise for my liking.
