Just how much extra work is there with Octane?  There was a thread resurrected not too long back (or I found it in a search) about the plug-in with Poser.  It's been out for a few years now so I'd think it would be more mature.   Are you using that, and the latest version?

 

I only ask because it sounded very interesting, it would be cheaper for a 2, 3 or 4 SLI computer rig vs. a server rig for the rendering power.  As a bonus, you have a monster gaming rig, or if you don't use it for that, can sell it secondhand without as much loss.
