I have a Samsung SH-S203 DVD burner I'm trying to put into a Dell Dimension 4600i. I open the case, first, I've never removed a CD Drive and I couldn't even take it out even though I got the screws out, apparently I'm supposed to pull it out the front but I have no idea how as the case doesn't come out, and, second, when looking at the new DVD Burner, it had two cables that come with it, the black ends fit PERFECTLY into the DVD burner, however, where do the ends that are supposed to be plugged into the computer go? It is SATA. I have no idea what to do. I tried some online guides but they did all but tell me the answer.You either have SATA port on your motherboard, or you'll have to get SATA to IDE adapter.
In any case, wait for some hardware guys for more advice.Dell's guide to REMOVING or installing drives in your model:

The cd drive should slide out the front if you unpluged everthing. I wouldn't take out the cd drive just in case that the dvd drive ever fails. But you can. There are three connectors on that cable asumeing that the cd drive has one you dont need to use the cable unless it fails. You can simply plug the drive on to the second connector. Then connect the power a small four pin female connector. If you already removed the cd drive look for a 40 pin connector on the motherboard which is the board everything plugs into. The one end connects into it. Then mount the drive and you should be able to use the drive.
