Once enough parts have been scrounged to assemble an extra working computer, Ohki could use either it or the pre-existing computer as a render slave ("remote", in Poser Queue Manager terms). That would enable you to offload a batch of promo renders or animation frames to the remote(s). You might also install Queue on your spouse's computer and the kids' computer. There is no limit on how many remotes onto which you may install Queue.

Here's a simplified diagram; where I have an unmanaged network "switch", that is often incorporated into a single box along with the modem, and called a "router".

On each remote, run the P11Pro installer, but at this window, change from the default (which installs Poser) to install only Queue Manager.

The first time you use the remote(s), your security software will challenge you for firewall permission. Give Queue Manager and FFRender64 firewall permissions!

I also have Vue's render engine and Lux installed on my remotes. Both of these render engines will distribute a single tough render across your network. Currently, Poser's Queue can only send the entire render to one remote, but cannot distribute buckets/samples across all of the machines in the network. My top Poser enhancement wishlist item is the ability for Queue to distribute buckets/samples across a network, so that all of your machines can cooperate on a single high quality wallpaper render.
