+1 on this. I ordered latching on accident for my first build.

(reason you want it this way is so when you press the button it turns on the computer then when you press it again it will run the windows shut down procedure (if you set it to shut down on power button press in the windows settings)

Problem with that is there is no corresponding setting for SHUT DOWN so when you power off it could cause corruption of the files.

Just let the FrontEnd shut down Windows...

Does that work though ? -- The BIOS setting restores power on power loss but if windows is shut down properly it turns the system off without noting there was a power loss so would then just sit there with power and not be set to boot back up or if set to restart after shut down would again start to boot right after the FE shut it down thus turning the power off would need to be done during the boot process which could cause system corruption (esp. if sya windows was starting to do an update if network connected)

Today I thought about start-up/shut down and came to the same arrangement.
Under my flip-up control panel I will have a mains power switch, and switches for the marquee lighting. Also the amplifier front panel will be accessible (power, volume). This will let me power off the PC and amp, but leave the marquee lit up for mood lighting :)
Also under there will be the only button to exit the frontend.

my optiplexes boot on power regardless of clean or dirty shutdown.
