Potential water damage to desktop computer

Last week, I came to work and they said a pipe burst over one of the computers. I assumed all the technology was tested thoroughly.

Today, I noticed that there was a light flashing in the back, indicating that it was at least getting power. Curious, I unplugged it and plugged it back in, then turned it on. It was back to life. The keyboard was useless, which we replaced, and the right monitor, which still needs to be replaced. (That might be a connection issue. The monitor still turns on and the entire screen is there. I'm just not getting picture otherwise.) I want to know if there are any issues I should be on lookout for.
