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.
I whouln’t replace the existing PC cooling or connect the air pump directly to it. Just something to suck out the hot air behind it. Even just a vent on the desk above the area might work.
Like a box fan above the computer connected to the tube that goes outside… Wait that actually sounds really easy and cheap.

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.
