A PC is pretty much a space heater these days. Which is not great when it gets all hot and humid outside.
Many suggest just getting a small AC but why not remove the heat from it’s source and put it outside?
I imagine the vent being much smaller than the big AC tube pictured.

You can get inline duct fans for not too much, but they do make duct adapters for the fan holes in the case.
I’d recommend running some stress tests with just the tubing to see if it’s sufficient to cool your system. You don’t want so much airflow that you’re causing your AC to run more often.
