so i found this old imac, one of those candy bubble drop looking ones. its blue and has a cd slot loading component (where you stick the cd in and doesn't have a tray that comes out). im not sure on the specs, but everything seems to work fine.

im interested in upgrading this to a good g4 processor. stick in a some more ram too. i dont think ill need more than the 5 gigs of hard drive space that's already on there though. my question is: is this possible? how can i do this? i figured once i can upgrade the processor, i can just load up mac os x and have a new mac. am i disillusioned? is it as easy as just buying a fancy g4 processor and sticking it in along with more ram? any links on step by step guides on how i may do this?

thanks guys.

i'm sure if they have g4 upgrades for that mac but i do know between that and the ram and the HD you are close to $500...

if you get a mini the keyboard and mouse would work... you would just need a monitor.

This is the only G4 upgrade that I know of for the G3 slot loading iMacs:

It is expensive at $299 and you have to send them your motherboard. By the time you upgrade the RAM and processor you could have spent a few extra bucks and get a new Mac mini.

NOT worth it. Get a Mini and a cheap display.

You cannot upgrade the processor in a slot-loading G3 iMac. You can add RAM, and you can upgrade the drives, and that's it.

This upgrade is not really a good deal. The G4 is only 500 MHz, without an onchip cache. The motherboard is still the same, so it's the old 60x bus rather than the newer MaxBus version used in current G4s. It's a 7410, not a 744x/745x used in current G4s - the main difference is that the Altivec performance is much lower. No, this upgrade will not bring the iMac to even half the performance of a Mac mini or low-end iBook. You can add more RAM and replace the HD, if you want, but other than that you should get a new machine rather than trying to upgrade it.

Heh, that's what I get for writing the reply when nobody else had replied yet, get distracted for a few hours, and then press "post"!

But I agree that it's not a cost-effective upgrade -- CPU upgrades often aren't.
