Hopefully this is message isn't considered "hijacking" a thread. I am building TWO gaming machines. One for each of my boys. The case I selected only have two fans and I am concerned about heat management. Generally speaking, what is an acceptable temperature inside a computer case? Any advice on heat management?
For air cooling, placement of case fans (and flow direction) is at least as important as the total number. Cases are designed with exhausting hot air in mind; obviously, some will do it much better than others. Earlier in this thread I posted a link to a really good article on case fans that is worth a read.

Modern CPUs are much better equipped to work under higher temperatures. It is not unusual to have CPU temps reach 80+ C during a long, intense gaming session. However, some of the other components (e.g., motherboard, RAM -- especially if lower quality/not specifically aimed at the gaming market) might not be as tolerant of a higher sustained operating temperature over the long run (whatever that might be in your situation). FWIW, AMD Ryzen 3xxx chips will start to throttle at 95 C (built-in protection), not that you would want temps to reach even close to that level. Running cooler benefits all components.
A few items for your consideration:
1. Don't try and cram too many items into a small(er) case. IMO, impeding airflow can cause more thermal-related problems than anything else, other than a poorly (or non) operating fan.
2. If possible, use a modular power supply so only required power cables are used. Fewer cables to obstruct airflow. Also, make sure the power supply is sufficient

3. Use an SSD rather than a mechanical hard drive. If the motherboard has a slot for an NVMe SSD, even better (no cables required).
4. If overclocking, install a quality after-market CPU cooler.
5. Add additional PWM case fans (if needed) and make sure all are working together. There is often a small arrow on the fan frame indicating airflow direction. The traditional approach is back & top case fans exhaust out, while front and side case fans are intake. The design of the case will largely dictate placement of case fans and airflow direction.
6. Read reviews about motherboard thermals. You don't need top-of-the-line performance but buying a MB that has poor thermals will increase the probability of disappointment sooner than later.
7. A dedicated graphics card adds additional thermal considerations. Some cards/GPUs run hotter and require more power at load. Once installed, set appropriate fan curves using software (e.g., Radeon Software Adrenalin, Nvidia Control Panel, etc.). Your budget and the types of games your sons play will largely dictate what GPU to get.
Have fun with the build. Perhaps your boys can assist and learn a few things along the way (or vice-versa, lol).
