That's a Scott Genius. It was a kinda novelty bike in its time in that it had a rear shock that sucked, rather than pumped. By that I mean it worked by extending the shock, rather than compressing it, as we're used to. That means that no other shock in the world can be used to replace it, should it go wrong. And, wrong they go. They have a zillion moving parts and tiny, tiny O-rings that fail rather frequently. Very few people know how to service that shock and comes time to service, you're in trouble.
For that reason along, I'd say your bike is worth far, far less than you would expect from a bike that was once upon a time, a premium bike. The concept never took off and Scott abandoned its proprietary shock for a standard push-to-compress style, albeit another rubbish brand - DT-Swiss. That also backfired on Scott and now it uses Fox products, if my information is correct.
Your bike looks to be in a niceish condition with top-end components. Hover, the proprietary shock and outdated 26" wheels devalue it.
