I have a recently retired HP DL185 storage server for sale.
10x 1TB WD Black hard drives
2x 500GB WD Blue hard drives
HP p800 raid card w/ 12 bay SAS expander.
All drives come with caddies that fit in to the chassis.
I believe it has a dual core AMD and 2GB of RAM.
Forgot to add price. 200$ seems reasonable.
