My old Node 2 in the great room system is usually listed for $300 average used and this Node which is two or three model years younger goes for around $400 on average used. At $250, I would have been insane not to pounce on it.
This unit replaces the Iomega with a 2TByte drive. I've got about 75% of the 2TB space filled up and accessing music on any of the large folders in excess of 450Gigs such as the Rock folder, causes it to reboot. I split the Rock folder into two which stabilizes the behaviour but updating music on it would become a royal PITA.
The Node in the basement connects to the Node2's USB attached library, (Western Digital 3TB) in the greatroom via the network. That would be the white box sitting on top of the center channel. The USB drive sits behind the center channel.
