Mac mini startup

I´m using a mac mini 2012 to run my nanohog4. I want to put it inside a flightcase, but theres a problem. When the mac get inside the case i would be a hassle to put the hand in between to start it. Is there a way to get the mac to start when i connect power to my flight case? I know about the thing with start after losing power function. This will not work if you turn the mac of before you take the power sadly
Any ideas?
Thanks in advance

Thanks in advance

Found online when searching for Mac power on keyboard shortcut:
"This used to be possible with the old Apple Desktop Bus connections, and for a time when Apple shipped a special USB implementation with a power pin, but it was removed with the Apple Pro Keyboard (model M7803) in 2000."
