The last machine I had with a power switch even near the rear was an old
286 that had the switch built into the side of the power supply and it
was at the rear edge of the case side. This was pre-AT days.
Feel free to modify any case you have to put the switch wherever you
want. After all, it is a MOM switch and the leads allow it anywhere you

For those who do not already know, most BIOS have an option on the
setting for the power on switch. It can usually be set to "instant off"
or to require a 4 second delay before it powers off. The newer boards I
have gotten seem to default to "instant off".
For the reason you quoted, I habitually set mine to utilize the delay
feature. The wee ones do not usually hold the button for 4 seconds
continuous as required for a shutdown with that setting.
