I'd guess right around $1k, give or take. Maybe more or less depending on where/who you sell it to.
You would get more money for sure by parting it out, and selling it like that.

and how much do you think if I sell it part by part?

Look up the "Current" prices on the parts and subtract at least 10% since yours are used parts.
