Does a Dell 755 have cpu socket type LGA 775 and sata II for system wiring?

I couldn't verify elsewhere. I'm hoping a Dell user, 755 user, or etc., would know. I've seen the forums asking about processors. Refurb place I bought my 755 from doesn't know.

I'm new here - What's the difference between labels and tags when posting?

Thanks,
