I have inherited a brand new pc from a friend and have a question about sata. The mobo has only one pci-e slot and that is being blocked by the video card. I need a connection to my external hdd enclosure. The mobo has a single free esata port and a couple of free sata ports. So what I beleive I need is something like, or similar to, this Click Here. But I am not sure if I must plug it into the esata port or a sata port of the mobo Or if it makes a difference. Thoughts??
