I have an Indigo iMac G3 that I got for my little one to play around with. It has OS 9.2 installed on it but I would like to put OS X on it. Which version (.2, .3, or .4) of OS X do you reccommend. Of course Tiger would be great but after all he is only 5 years old. The specs are 400Mhz, 1GB RAM, and 10GB HDD (will get larger 40 HDD soon I hope).
