Police say the man stuffed the computers into a duffel bag around 3pm Thursday and as he walked out of the store, an employee confronted him.
The suspect pulled a knife and threatened the worker, who backed away, and the suspect drove off on a white-and-green moped or scooter.
He's described as white, 30-40 years old, with an average build and a full beard, wearing a tan jacket and jeans.
Police are asking anyone with information to call Troop 2 or CrimeStoppers.
