Also, do not get an external hard drive. Get the extra hard drive but make it an internal one. It will not only save you cash but is more likely to be supported by whichever s/w manufacturere you opt to go with.

If you can go more than 150Gb then that would be better. You'll be suprised how quickly it gets eaten up.

Oh, and make sure whatever PC you get has a firewire port on it.
