I have a 2003 Dell Dimension 4600.  Hard drive has crashed.  Just got a second that is a SATA drive.  I was not told by Dell that the cables would not fit with my existing computer - so, now I am wondering what cables I should use.  Computer currently uses a 4 pin power cable for the drive so I can get a converter for that.  But what about the data connection?  The current data connection is a very long gray bar that has 20 rows of holes for pins to fit into.  There is nothing that I can see what would fit this new drive that I have (which is a Western Digital 250GB SATA 8MB Cache)

On the label there is a picture that shows a serial data port with S7 - S1.  Any ideas about what cable or adaptor I would need for this?

Also, Dell rep told me that this would be plug and play when I purchased it.  Anyone know if this is actually true - or if I will have to do other work on it?  (I am not very knowledgable about this stuff.

Thanks in advance for the help!
