For Sale - ReadyNAS NV+ RND4000 system - $100 plus shipping and insurance.
This unit is easy to configure on your network for reliable storage. You can attach additional external USB drives to increased capacity and flexibility. I don't use it on my network since switching to Macs.
Excellent condition.
I live in North Wales, PA, a Philadelphia suburb, if you want to see the unit in person.
Cheers.
