I paid $2200 for mine back in 2014. It had no CPU.
HUO, and better yet, it had been sitting broken (SUPER-botched CPU repair) since ~2004.
I would put the market value of this particular machine at $4000, but I wouldn't sell it for that. It's my third Godzilla. I traded up twice to finally get one in this condition, so it stays forever unless the rent isn't paid.
