You could get the NAS alone for $400 on the eBay sales but for slightly more you get 2 x 3TB ironwolf hdds worth $162 each. This is amazing value!
This is a great value NAS with an intel processor inside N3060 and dual lan. This model comes with 2gb ram but can be upgraded to 8gb.

Edit: it's still available, just ensure Amazon is selected as the seller. A few people have jumped on this deal as initial stock has gone and next batch will ship in 2-5 weeks.
Wow, great deal. I got the TS-251 and one 3TB drive separately for $475 last year. Though unsupported, I upgraded my RAM to 16GB.
