Cool, thanks guys. I think through the help of others here in the last thread, we found my model was "MacBook2,1" or something like that, which I guess puts it as a late 2006 or early 2007 model. It looks like those max out at 3GB, so I assume I get two 2GB sticks and it just uses what it can?

I might just jump on that refurb SSD I posted about. I know I said I didn't need a lot of space, but the best space/value I was seeing was around $60 for ~60GB anyway, and I'll take more space if I can get it
