posting as reference. here are three ways to move files, listed in order of overall speed of the operation (even if hard drive to hard drive would be the fastest way from a data-transfer perspective).
if you're security-minded and have disabled sharing and such, which makes your network invalid except for letting the router farm out IP addresses, just sign up for an AIM account, then get another one. log on with one ID on one computer and the other on the other, and then just send the files to yourself once you OK the firewall warnings (you do have a firewall running, right, haha). the program figures out that your other machine is local, and you get amazing bandwidth, ie 2500 kb/sec. it doesn't take long to move several gig by this means.
if you have two desktops, you can just pull the hard drive from the source, temporarily plug it into the destination PC and grab the files that way. (do that if you're not afraid to get your hands dirty, figuratively speaking, and have something against getting an AIM ID.)
there are also PCI-to-USB2 adaptors that allow you to "see" a remote computer as a drive from the destination computer, essentially making a makeshift network.
