That tiny magnet isn't going to do any harm to a system when its on the front of your case. I think its a neat idea, but would get annoying after awhile.

u would think that magnets would be bad in a computer but the HDD actually have a realy powerful magnet in it. its used to move the heads and is only bout the width of your thumb away from the disks. a tiny magnet used for this wouldnt do anything really.

what about this. u put a magnet over the reed switch to turn it on/off. works jus like a normal power button.
the ground is the other wire on the power switch.

EDIT btw u wouldnt need 2 keep the magnet over the reed switch 2 keep the compuer on if u hav a modern "softswitch" board and not an old style switch that comes from the PSU EDIT

even simpler all you would need to do would be to replace the push switch with a reed switch and it will work jus fine.

orion, that circuit at qprox is a nice find. i think it's worth $20 to not have to use magnets or lights. it even has external power, output, and both momentary and toggle modes. alls you need to rig it up is an Vreg like an LM317 to get 3V power to the thing, unless the ouput isn't ground reference (then you'd need an optop-isolator).

if money is an issue & labor isn't, you could buy the QT110-D for under $2 & build the board from their schematic.

if you use the light idea, you could hide the light sensor behind your case badge if you have one.

Thats a good idea, ill try that one out when i try the mod cause i dont have a badge right now and ill just put some dark plexi as the badge and the sensor attached to the plexi.
