Question : Add second monitor to HP Touch 300z

Has anybody added a second monitor to an HP Touch 300z series (all in one style PC)?  It doesn't look like there are any expansion bays like you would have on a tower, I searched for a solution and it looks like the answer is either no or it's so complicated/expensive it's not worth it.  Just wondered if anyone has done this succesfully.  Thanks.

Adding a second monitor is simply not an option, sorry.
