I understand I can upgrade up to a gig. I see the ram that is on top, but where is the other ram? What kind of ram should I be searching the web for? Thanks!

The second RAM part is under the board that holds the one you can see.

I like to order memory from http://www.a1acomputing.com. Here is the page; choose your computer speed. http://a1acomputing.com/pbg3memory.html
