The noise sounds like the fan is rubbing up against one of the radiator blades...  Were there any leaks with the water cooling?

So far, 1/1 units appear to have significant damage upon arrival.   Is anyone keeping a tally?  Might not hurt to start one.

Also - You might want to consider giving them a call to discuss a warranty claim (i think they only warrant these devices for a couple weeks).  At the very least, they can start to resolve the issues and they may end up shipping you a replacement unit.  Sounds like they have very serious issues to resolve.
