I run the headphone jack of the PC we use for internet into a Yamaha AV amplifier and a set of stereo speakers. It's not an audiophile system but it's much better than PC speakers.

It would be really convenient to stand the amp vertically to save desk space. But it has vents top and bottom, none on the front back or sides.

Can you run these vertically? or do they need the airflow from the bottom to stay cool enough?


Could you remove the top cover of the amp , cut a hole in the side that
would become the new top face and cover that with a fan grille or
similar mesh? A matching lower hole would not be required, assuming
there will be airflow into the original air vants
