You have come up with many valid points. The suggestion of changing case orientation is really only for leak testing, but your response was so lengthy that I feel I should address all of your points. Also, since you don't speak from experience, I have returned your disrespectful sarcasm with some more.

1. I think some case fans solve the heatbuildup problem. You test it with a fully watercooled pc (CPU,GPU,North) and then get back to me. I want hard data, not your opinion.

2. We agree on the spraying water being catastrophic. OK.
2a. Everything is NOT below the mobo. Water will go straight down in the case of drips, and there is nothing directly over my sockets except for the case lid.

3. Your sarcasm is unappreciated. I am well aware of gravity. I have not only thought about mounting things upside down, but I have also done it. I see in your signature you WANT to have a watercooled system, so I don't respect your opinion.

4. Put your pump-res-rad in a separate case ABOVE the PC, and the CPU blocks are no longer the highest point. Case closed (pun intended).
4a. Will the heat transfer suffer because the block's weight and the water within pulls it away from the die? I have definitely thought about the mounting system, and my waterblocks are going nowhere.
