AHHH. Are you like screaming? Check your caps lock man! :)

I have thought of the same thing with my 350mhz.

They are not compatible, but you can mod the heatsink to be on top of the processor so that it does not explode.

Please noooooo Caps.

sorry hahah when you say mod the heat sink ........ what would happen if i just used the heat sink from my 400 and used it on the 600? is that possible? or is it in a different location .......and when you say mod does that mean cutting away plastic on the imac?

It means a lotta nasty hacking, involving glue and duct tape. Yes you could use your current heatsink but its not 100% guaranteeed to work.

well i only paid 30 bucks for that mobo do you think its worth doing???? the imac g3 dv graphite that i have is is excellent condition i bought it from the original owner with was a older lady that never used it so i dont really wanna get it all scratched up.

i actually work on macs but not alot of the older ones

i know how to whip apart a ibook g3 in like 5 mins

the things i work on the most is mac pros,macbooks ,macbook pros, intel imacs and g4 g4,

im just not goos with imac g3'?

about the only surefire way to tell is to pull it apart and hold the 2 motherboards next to eachother, notice mounting differences and clearance issues

Turn off your caps lock please.

Congratulations on your success. If you could put up some photos and details of the modifications you had to make, that would be terrific.
