Scamp: isn't it worth to turn in horizontal plane 90 degrees pump and use some less curved fitting (eg. some 90 degrees double(tripple?) rotary which looks like consisting of two 45deg). This way tubing should still look stright from side, and one 90deg fitting less ..
Hmm, i wonder if something can be done with last diagonal piece of tubing from cpu waterblock to mosfet one .. some smartly placed/turned 45deg rotary magic?
