You can get a SATA II terabyte drive for $80 if you want. You can put whatever you desire into an old computer; you shouldn't limit yourself based on what you think is 'worth' putting in there.
I dunno, you want it to be cheap, otherwise I'd suggest getting a SATA III 3TB drive for it. That way when you upgrade to a new desktop (if you upgrade to a new desktop), you can get the stock HDD with it and just swap the two without losing any speed on the new desktop (because those are all SATA III now) and only losing space on the old one.
But again, you said as cheap as possible, so I'd say grab a SATA II 1TB drive.
