PC on r9 Stygian Reaver

Hey hey,

So I picked up stygian reaver from z-chest (woot)
I'm a noob when it comes to selling shit, so it's unid at the moment.
Need a PC on it. Also, if I keep it unid is it worth more/less, does it even matter?
Thanks y'all!

id it, 99.9% chance that it is inscriptable, and sell it for 80-100k these days
