How much is my PC worth?

[Hades11]

Considering selling my PC but have no clue what it's worth;

Intel i7 2600k 3.4 ghz
16gb RAM
Radeon 7870 2gb HD graphics
500gb HDD
450w PSU
Blue black coolermaster case with 2 case fans
Plays pretty much everything I have well,
Play CS:GO, Total War Atilla, Vermintide, Dishonored etc

I usually look at the prices of completed auctions on eBay to get an idea. See here (prices in US dollars):

EDIT: Auctions with prices in green means that the seller actually sold it for that price.
