what the heck is this noise?

Im looking at purchasing a 96 mystic with a terminator swap in it. The Car makes a weird noise while it idles almost sounds like marbles in a can (kinda). The owner had the car brought to a shop and does not believe it to be a Head issue but im not sure. Below is the link to the video https://www.youtube.com/watch?v=uVbEBArC-q0&feature=youtu.be

Throw out bearing, alternator, blower etc.... could be anything. You need to start diagnosing. Pull the blower belt off and start the car, see if the noise is still persistent.
