Summary

Made a PC power button pusher to wake up my PC.
Based it on my previous device that actuates a door closer.
Uses the same simple hardware (smart outlet, 12v adapter, and 12v solenoid)

Used a magnet to hold it to the case (amazon.com/dp/B07FL7NCYN)
Used a 555 timer to make sure it turns off after a precise time (amazon.com/dp/B01DK8NJNI)
Used a diode to make sure the relay release doesn't fry the controller (just about anything will work)
Used a thermal fuse just in case everything else doesnt work (amazon.com/dp/B09VYD1X83)
