IDE controller for SATA motherboard

I just bought a new gateway computer, which uses SATA drives. THere is no IDE slot for IDE hard drives. Do I need to purchase a PCI IDE controller?

Or buy an enclosure and use usb to connect it to your comuter.

if i want to use this internally, is there anything special i need to worry about in terms of finding the controller? i'm concerned about buying the wrong thing. Is it a straighforward purchase?

Usually they have at least 1 controller on the board for IDE.
Have you checked?

i did check and there is no controller (very interesting). I did order a PCI controller. THank you very much for your help.
