Just to post an update to my post above - I have to soften my criticism for Rigol a bit. I got a call from a guy there today - nice guy and he explained that the DP832 did have an issue and they were replacing boards on USA units. Apparently they are waiting on a shipment of repair parts from the China factory.
I don't think anything they told me was a secret, but basically they are keeping a list of USA customers who need repairs on their units. They will then be contacting us when it's time to send our units in.
More info here:

http://beyondmeasure.rigoltech.com/acton/form/1579/0014:d-0001/1/index.htmwhere you can fill out your info to get on their repair list (for USA customers only), and there is also a specific email address for USA customers inquiring about DP832 repair, that address is dp8repairusa@rigol.com
So if you are in the USA, fill out the form and then wait to hear back from Rigol.
I was told that my unit was the first one they have heard about having resetting issues (which only happens when I make it happen - i.e. put it in my rack, load it up and suck power from USB as well)... so to be fair, it's not like it resets all the time, but it does run hot as hell, measured way over 250F with my FLIR camera, so it definitely needs the upgraded board.
Just an FYI!
