What type of connector do I have?

I own  http://support.wdc.com/product/spec.asp?modelno=WDG1C3200N&lang=en 

I want to change to a new case, as my new computer doesn’t have a FireWire jack. Is it SATA or IDE (I’d like to keep the drive together until I buy the new case).

It’s the 320 GB 

model wd3200d032-000
