I have seen people get nice furniture second hand like a half cupboard/storage unit/etc from second hand shops and install racks into them and mount everything in there and cut some vent holes at the back.

For extra points wack some flowers and a photo of your wife on top with a doyley.

I have seen one guy even model the air flow on his computer to find the right ventilation setup

Tdarr is probably your best bet. Its main focus is video but it used ffmeg as the backend, so anything it supports is supported in Tdarr (theoretically)

You may need to configure ffmeg arguments in the tdarr step chain if there isn’t a default step you can use.
