What do I need to know about having a gaming pc on 24/7?

[monkeyofdoom44]

I have a new gaming pc and I made a program that will automatically play a game I have. I'm wanting to build a new pc to be on 24/7. I want to leave it on to grind in that game for a few months. I've also wanted to get into programs that will learn to play games on their own. To do this I'd need a computer that can run games but is also on 24/7. I'm not sure what a computer would need to run 24/7, what the problems of running a computer 24/7 are, or if there would be anything wrong with this, to begin with. What are the things I need to know and look out for?

Good quality MATCHED components, solid mains power feed with protection, and a clean environment with good cool airflow. As long as all the fans and heat sinks are kept clean, temperatures are monitored, should be no problem.
