Nice score! This is a good time to be rescuing G3 iMacs because they're getting long in the tooth and plenty of people are selling them for next to nothing, or throwing them away.
This will change as time goes on and I expect G3 iMacs will become collectable novelties in the future. I would like to get one of every colour made but I just don't have the space!
I want to do that same but only get one of each color that has firewire.
I would also get the 233MHz iMac because its the original.
I want to do that with each mac line. But only do it with each model name like PowerMacintosh (the beige 8500 and 7600) I wouldn't get each one just because the speed is slightly different. Only case designs I'm really after.
