How difficult is it to self-install additional RAM in an LCD iMac? I am interested, with the release of the 20Inch version, to buy one for my wife, but the cost of RAM from the Apple store is unjustifiably expensive - but I'm wondering with these things, how difficult it is to install. In a normal deskop you just flip off the cover and away you go, but I'm concerned that in a machine like the iMac, it's not that clear-cut.
Anyone have some personal experience?
Cheers,
WJ.
