i bought one of these the last time they were on sale... holds my iGo keyboard and n800 perfectly. The whole package accidentally fell out of the truck (~ 4-5 feet) onto a stone walkway the other day; no damage whatsoever to anything. I would recommend this case to any n8x0 owner.
it's the Case Logic "portable HD case" I don't know if it has a model number... I'm not seeing one on it, and the packaging was tossed before I left the store with it.
). I can definitely vouch for its awesome.
