My PC is silent under water and performs 5 times faster than any mac in existence
Under water? You mean water cooled? Expensive and most people won't even attempt it. Most people on this forum don't even have water cooling not even considering the general public. And since Mac's are quiet and can't be overclocked what would be the point in watercooling it?
What is your spec? 5 times faster than the fastest Mac Pro? That will be a great machine if true. Irrelevant of that you are probably in a less than 1% niche that means a Mac isn't suitable.
