Help with squealing sound!

[br3g0]

A week ago I bought my first Porsche, a 2000 Boxster S with 48k miles.

I cant seem to figure out what the squealing noise I am hearing intermittently.

I hear it typically at speeds greater than 30mph. It 'goes away' when I brake and drop overall velocity below 30mph.

Loose Belt?
Wheel Bearing?

Any help at all would be appreciated!

Thank you,
