I have a first gen mac mini (Core Duo 1.66) and it is still chugging along happily. But seeing as how I'm getting left behind with Lion, I am wondering about upgrades. I've heard that people have successfully upgraded these machines with T7200 Core 2 Duo procs and 2 GB of RAM. I've also heard people upgrading to 3GB of RAM using 2x2GB matched pairs, but I don't know if those were with a newer version mac mini. So my questions are: Is the amount of RAM limited to 2 GB by the motherboard on these older machines or can I slap in a 4GB matched pair? Following that, if I upgrade the CPU and the RAM to Lion specs, will I be able to run it? Thanks!
