I not very good with hardwares, my mobo is quite old - I think there is only one slot, dunno whether it is a PCIE or AGP slot
. BTW if can add extra SATA slots, how do I place the extra hdds? I got 4 SATA and 1 IDE piled up together now. Is there any external casing that can hold and connect the 4 units together sort like external hdds with usb link to my pc? I would like to use them as backup units. Data transfer rate will be slow, no other choice.
