I'm building my first PC using a vintage late 90s case, and I want to keep the exterior untouched for nostalgic reasons. This makes accommodating airflow for modern components a bit tricky. My idea is to cut into the back and bottom of the case for fans and a small AIO radiator, but I haven't picked my cooling gear yet. I've sketched out some designs which you can see [here](https://imgur.com/a/airflow-details-diagram-1VTsUZk). Does this overall plan make sense, or how can I improve it? I've learned quite a bit about PC building this week, but I might still have some misconceptions.

What CPU and GPU are you planning to use? That compact AIO might not cool a high-powered CPU adequately; you might have to consider going for a custom loop. Honestly, I'd recommend a case like the Silverstone FLP01 for better airflow, but if you're set on your current case, just keep an eye on those temperatures. A small AIO can lead to problems if it can't handle it.
I think it could work to cut into the bottom, but I'm not so sure about the back. Why not swap your setup around? Make the front and bottom fans intakes, and let the rear handle exhaust. Assuming you have a top-mounted PSU, it should help with airflow. By the way, does your GPU blow air out or draw it in? That's something to consider, so you don't have conflicting airflow with your bottom fans.
To simplify your build, just flip the fans! The classic setup is front/bottom intake and rear/top exhaust. About that AIO, two 80mm fans just doesn't cut it, so I suggest looking into a conventional air cooler instead. It's usually more efficient and will fit better in tight spaces.
