I do have another question.

I will need to transfer the data from my current computer to the new one.

I do have a router, but I can't remember the password and stuff, and the OS on each computer is different (current desktop has Windows 2000) so setting up a network isn't straight forward because I tried to do it between my desktop and laptop and couldn't manage to get it figured out.

Anyway, I think you can do it by direct transfer using some kind of cable.  What kind of cable do I need to get in order to do that?

heart whatever they might have to say." - Ghandi
