Looks pretty hairy to me. Pry the case open with putty knives, remove the airport antenna (and bluetooth antenna I think), remove the optical and hdd to get to ram slots underneath. I have built and worked on many pc's, so I'm fairly competent with computer hardware. Does it just look harder than it is? It doesn't actually look hard, just the risk looks high to break something in the process. There was a very detailed guide somewhere, but I can't seem to find it. Anyone have the link? Also, which slot is which? Is the one on top 0, or the one underneath? I was going to put in a 1gb stick while leaving in one of the 256mb sticks. And with pcs, if you had 2 sticks of different size it was common practice to always put the larger stick in slot 0. Don't know if that holds true with the mac or not though.
