I saw a guy's page on this months ago .. the link is dead for a long time now .. it did include a lot of dremel work and the door wasn't spring loaded ..
thanks for sharing that mertzen. This piece of information is great to prove my point, . the reason for macmod and its purpose. If everyone would take the time to post their mod guides on our site, these would not get lost in the ever disappearing world of websites. It is a shame that so many great mod guides, that could assist so many other modders, are no longer around due to this reason. This is also why macmod stresses posting your images on our server for hosting. Not only is hotlinking wrong, sites like these go down, and when the images are gone, the mod guide looses most of its value. So, take this as a lesson, contribute to the macmod mod database, and help the mac modding community. :P
Ok, I am done now

I have a graphite G4. Your main problem will come from your heatsink. The RAM is located on the logic board in such a way that it is actually above the optical drive when closed so no worries there. The heat sink will provide only a minor headache if you are serious about this mod. I have a OWC G4 700 upgrade and it comes with an L shaped heat sink with a fan located on the side of the L that is not on the processor.
Even with this setup, a 5.25 drive would touch the heatsink. You will have to resort to a custom heat sink and no doubt have a fan attached to it as well. Its very possible, just a bit more difficult that I originally anticipated.
