Help pricing 3070 Prebuilt?

Hey, I have a prebuilt PC that i'm going to be selling... NOT ON HERE INCASE THAT VIOLATES ANYTHING!! :)

Can anyone help me value it? It's not the newest but it has decent parts inside in my opinion, preowned market is all over the place when I tried valuing it myself so I thought it'd be better for the more experienced redditors...

Weird Request but i was thinking it might be smart for me to sell 2 of the ram sticks, and then sell it with 16GB or 32GB opposed to 48GB due to the insane ram market atm. So if anyone would be willing to value based on if it had just the 16GB Acer set, just the 32GB Corsair set, and all together that would be amazing. Thanks <3
