Another option is to install a third 2.5” in optical disc drive caddy which has same form factor as a slim dvd.  this way you do not need extra cables. [IMAGE]  
Hello, I havea 5060 sff, removed optical drive and have 2 2.5 drive mounted on a caddy. I have free sata ports on the motherboard, and was wondering wether I might put a third 2.5 drive in the optical drive space with an adapter. My question is: is there a particular dell 6pin sata power cable I need to use to power all three of them? I don't currently have spare power cable, just two of them. Many thanks
