Upgrading memory on a Mac Mini G4

Well, the day finally came to upgrade the memory on my father-in-law’s Mac Mini. He was running with 512MB and it just wasn’t cutting it any longer, plus I wanted to upgrade him to Leopard so more memory seemed like a good idea. Getting the extra RAM was the easy (cheap!) part, but once confronted with the Mac Mini itself I couldn’t figure out a way to “crack” it open. Thankfully, I wasn’t the first person to run into this problem, and there are many how-to’s online. Two word: putty knife. =)
