So I just got an el cheapo ($250) 400Mhz iMac G3 off of craigslist.org and it's great! It took me about 2 hours to wipe the HD and clean install 10.3.5 on to it. For being a G3, it handles Panther pretty well. I plan on using it for iTunes streaming and internet, so it definitely doesn't need to be a speed demon, and the 10GB HD is plenty. I just wanted to recommend to anyone that wants another computer for all the simple tasks, that this was a really great and inexpensive solution.
