Can you run a water cooled computer on it's side

Try contacting the manufacturer of said computer.

I need more detail then this

I don't work for Micro Center, I just wrote a review. I didn't even know that there are water cooled computers. I recommended asking Micro Center. I found that by going to their website and using their Chat utility to request a computer Dept expert to contact you by phone or Chat worked the best and it was the fastest way to get answers to my computer questions.
