The problem here is if the thief is technically capable they will have already wiped the hard drive and it's unlikely any trace will be found.
But a lot of thieves are not technically capable and it's why they are thieves instead of IT staff...
You have a slim chance of recovery - if the thief has not wiped the hard drive.
My friends, the Melins, had their stolen laptop recovered because Seti at Home was installed on it which periodically calls home.
The authorities were able to track the location by the IP address the computer was reporting home from and it was recovered from the thieves.
