First time builder - wiring question!

[Janelle]

Hello again forum! I previously posted asking for advice on a case and did end up picking one and beginning my build. So far it's going okay, I think everything is scuessfully installed and wired except for the video card, saving that for last!

But, there is one thing I am wondering if I have done wrong. I took the sata cables from the motherboard and PSU boxes to install my WD Caviar black 6gb/s HD and Asus DVD burner. I noticed from the beginning that in the bundle of wires coming from the front panel there were two flat orange wires with identical SATA-looking ends. But I figured that was related to the eSATA hub on my front panel. Now I am wondering if by some chance those two wires were supposed to be plugged in to my devices?

I do not really know how external SATA drives work yet so please forgive my ignorance. Pleaaaase tell me I didn't do things wrong and I was not supposed to use those on my internal devices like the HD/Burner? I wonder where the other ends of those wires are.

Case: CM 690 II

Thank you kindly for humoring this noob.

The cases manual should tell you what they are for sure, but I think you are right in assuming they are for some frontpanel connection, they would be plugged to the mobo, and not into your optical or hard drives, those get connected to the motherboard

The case manual says they are indeed sata connectors but no more information hehe. They ends that I can see look like the ends that go in to the device, which confuses me a little. I expected a wire that would go in to a sata port on the mobo.
