> I'm willing to risk taking it apart. voiding the warranty.

Main thing:
What's wrong/broken??

If the machine is still under warranty (normally 3 years, certain
entry level models 2 years only) why not have the machine serviced by
HP?

You may check warranty here:

> is it possible to buy parts for it?

Yes, to a certain extent.

> does anybody or anywhere sell them?

HP. Pls see their Parts Store:

Another source might be eBay. There are "ruins" sold for parts offered
from time to time.
