@HurricaneX As Apple officially only caters for the maximum of 15 ports in Macs, the general consensus is that we should aim for the same or less.
as @miliuco pointed out there is nothing wrong with having more than but you can/may run into issues with some USB or other related issues having that many.
If you're happy with the operation of your machine, by all means carry on, as the saying goes........'One man's meat is another man's'......... etc, etc.
Cheers.
