Does not come with hard drive caddies. There's no point in ordering a server for 2 day delivery if you have to go back to the manufacturer to buy a little piece of metal to get a full machine!?!?!? I search the page for any notice of this deficiency. I only found it on a lenovo support site.""the RS160 does not include the hdd caddies. they are not sold after marketthe only way that you can obtain the drive bays and power cords for the drives id to purchase directly from Lenovo options as a complete assembly""So if you buy this be sure to purchase some 2 sided tape to keep the disk in place.

With an M.2 port you can get this thing up in a matter of minutes, but you will need to buy separate hard drive caddies or find some other means of adhering any non flash memory to the hardware.
