I would like to, some day, leave the PC and Windows behind and move onto pastures new, but, when I looked at an E-Mac something struck me. How on earth do you upgrade the thing? Keyboard and mouse... ok, but what about a graphics card? Sound card? I know you can't change the VDU without buy a new system (give me some credit), but what else can you put in it? Any information (as long as it is correct, naturally) is welcome.
