Decided to update this, since by the time that I ordered my case the casecrown above was OOS, so I ordered this one instead:
http://www.amazon.com/Professional-B...5714924&sr=1-4
Uses corner securing system with the right side corners being leather and the upper one covers the volume buttons. Left corners are elasticy material, upper partly covers power button, but it's still accessible and will probably not inadvertently actuate the power button. Holds it securely. The strap is a magnetic closer which holds in place very securely.
Probably end up with an actual B&N case which uses a different style of securing the NC in the case. Still might try to track down another casecrown NC case as well...
[EDIT]
One other drawback is that the case does have a bit of an odor although not nearly as bad as my neoprene case from Sears for my gTablet had...
