resurrecting a RNV2-S2-0000

I found an old RNV2-S2-0000 that a co-worker was throwing out, and I was wanting to reuse it. bad thing is that it was only the box. I would like to know if I could buy the lockable trays for it? also what Hard Drives are compatible with the RNV2-S2-0000 and are they only RAID drives? cause I would like to use it as a home network storage server.
