I read what you wrote and still thought the comment was necessary. Apparently so did several other people.
Look at all these people taking your manager's side even though 1. we have an initial prejudice in your favor because you are a fellow K5er, 2. You got to tell the entire story from your side, 3. the boss wasn't even able to tell his side, and 4. many of us have done similar work for bosses we didn't like. Doesn't that say something?
Isn't it even remotely possible that what really happened here is that you got into a pissing contest with your boss and lost? I'll bet you already had problems with him because he wouldn't take your advice on technical issues. Maybe he was wrong not to, but that doesn't change the issue that at some point you began to take it personally.
A responsible sysadmin would have moved everything the very night the leaking started without waiting to see if the boss was going to take his advice about the new air conditioner. That dangerous server room wasn't the boss's fault, it was yours. As the sysadmin your job is to create the most robust system you can with the resources you have. Leaving a dangerous situation in place to protest against your boss is a dereliction of duty so serious that I would consider firing you on that basis alone.
Seriously, dude, you don't need revenge. What you need is an hour to sit down by yourself in a quiet place and try to visualize how you look to other people. Especially the people who don't seem to like you. I can guarantee you from experience, it will be one of the most rewarding hours of your life.
Everybody relax, I'm here.
