I installed a Seagate Barracuda SATA 7200.10 hard drive which is connected to one of the 7-pin ports using a 7-pin to 7-pin SATA cable. I have 4 external SATA hard drives. I've been looking for an adapter/card that I could install so that I can connect the hard drives using a SATA connection but I haven't been able to find one anywhere. It isn't possible to connect the port card in the usual way. There is no SATA connection near the rear of the case. I would have to purchase one that has a plug so that I can connect it the same way I connected the internal hard drive.
The first picture is the motherboard and the second picture shows the SATA ports on the motherboard, and you can see where the ports are in relation to the rear of the case.
Can anyone help me out?
