Hey all. A friend of mine was just given an old 500MHz G4 PowerMac and I want to try and make it useful for him.. It has: - 640MB of RAM - 27GB HDD - OS X Panther (10.3) Here is what I want to put in: - Thinking of getting a total of 4 512MB sticks of RAM for a total of 2GB. One question here is if I can buy PC133 RAM (easier to find, might even have some at home) and if the computer would just down clock the RAM to the system bus of PC100 (which is harder to find RAM). - I have an extra 120GB drive from back in the day that is at least surely way faster than the 27GB that is in the system now. - I also am thinking of putting OS X Tiger (10.4) on there as well to give him a more modern OS, with the iLife '08 (or maybe '06 if I can find it) suite, since he wants to mostly use the system for GarageBand. So my biggest question aside from the RAM mentioned above, is Tiger and iLife going to be too much for the system? Is it all worth it? Thanks for the input! PS - this is my first time working with a non-Intel Mac! Woo!
