How much could I sell my homebuilt computer for?...

Hey guys. The time has come to sell one of my favorite (yet now antiquated) builds in preparation for my move to California from Sweden. I just won't be able to bring my homebuild with me to Cali as it wouldn't be practical or make any economical sense. Anyways, I'm gonna put an ad up for it later today but thought I'd ask you guys first how much you reckon I could get for it. I have no clue about computer prices anymore as this was my latest build, but I do realize that it probably isn't worth much anymore. I initially bought the setup 3 years ago and have been upgrading on it since.

The build:


I think those were all the specs, let me know if I forgot anything. Everything is running 100% fine, the computer runs perfectly at low temperatures and is virtually silent thanks to the huge fans on the HAF casing. Although I'm sure the computer is considered antiquated by today's standards, it has yet to have had trouble running the latest games on the market with medium-high graphics.

Really wish I could keep my build but unfortunately we must part   Anyone have any ballpark figures on what I should be asking for it?

Thanks beforehand.
