Have you access to an external hard drive? If so, you can connect the hard drive through USB and copy the info straight onto it. It will appear as a new drive.
Alternatively, does your work have 'shared' network drives? You could always use them as temporary holding areas.
If not, but you do have a network, you could put your laptop on the network, along with the old PC. Share the folder on the old PC and map to it on your Laptop. Then it's a simple copy and paste job.
Lastly, if your computer is banjaxed for some reason, you could get someone who knows what they are doing to remove the hard drive, put it into another computer and do any of the copying you want from there.
