Aurora R7, how to automatically start when power is on?

Question

Hello,I will not have access to the power button of my Alienware Aurora R7 once I place it in the cabinet I bought it for, and I need a solution to boot it.I was initially thinking of having a button switch in the cabinet with wires going to a 'power' jumper' on the mother board but I haven't been able to find it, would anyone be able to point me to it  on the attached picture or any pictures of the motherboard ?  (I found pics of the motherboard here : https://www.amazon.com/Alienware-Aurora-LGA1151-Motherboard-IPCFL-SC/dp/B07W988YW2  )An alternative I thought of is having the PC boot automatically when powered up, as the cabinet will be powered off most of the time and I will plug it into the power outlet when I need to use it. Unfortunately despite trying different options in the R7 Bios (AC recovery power on, autopower on for 'every day'...) nothing worked, the PC doesn't automatically start when plugged into the power outlet.Any other thoughts or suggestions most welcome ! Thanks !

you can connect custom power button switch cables to R7 LED controller pins for power switch (pin 3-4). For more details refer to https://www.reddit.com/user/ZwoukLeBleu/

R7: 1 2 3 4 5 6 7 8 9 10 11 12

disconnect the LED controller cable connector (carefully and gently, do not pull on skinny wires)

Do you have a cooling solution for this cabinet constraint?

Thanks a million @redxps630 that's great ! The only concern I have is that since I will need to remove the original connector shown on the photos I will get an error message when booting but it looks like I don't have an alternative. @ProfessorW00d I plan to leave the watercooling system in the Aurora and the cabinet will have one fan below to suck cold air in and another (very big) fan at the rear to push out hot air. I hope it will be enough.

I think you only remove the original connector to add a custom power switch . . . then plug it back into the motherboard.
