Chosen Solution

I recently bought a mid-2010 Mac Pro 5,1 from OWC and using it in one day the power button pushed in. It still kinda works. I have to be very careful about powering it off and on. I was using it a lot to upgrade to High Sierra. Needless to say, I would like to know where I can find the part or a guide on how to fix it. I would settle for just a list. Thank you kindly.
