WoW from a 1.1 usb port from an external harddrive.?

Personally I'm awed that you can play the game at all on a 9 year old computer. I wouldn't expect much, If you really want to keep going you could get a USB2.0 PCI card for like $20 or just replace the harddrive/take it out of the external case and install it as a secondary slave harddrive in your PC itself.
