Are you referring to the computer tower or the on-off switch as a CPU? Because a CPU - Central processing unit is a specific component that is about 1.25 inches and is underneath a heatsink and fan. It's sort of like referring to an engine as a car. Or the body of a car as the engine.

I notice you did not secure the switch plate to the case, which means you can pop the switch out strip the wires and just twist them together and your in.

You need to hot glue the switch plate in place or use screws so the place cant be puled out or pushed in.

yeah Qui great tat u ve noticed......but u see the pic, thr is a nut securing the key switch from inside so the switch cant be pulled out or pushed in.........

yes your switch is secured to the plate but unless the plate is fixed to the case it will pop out in seconds and you have access to the wires.

hi Qui.....the plate is non return press fit type....see the pic of the place both ends.....so it fits firmly to the case.....u can't touch the wires unless u break the plate........or, instead using the plate u can also make a hole in the cabinet case itself fix the switch thr..........

Good job. A hardware solution such as this is more secure than software for protecting an home or office PC from casual snooping. Someone determined enough would open the case.

It's ironic that this used to be common on the earlier generation PCs, but I havn't seen it for a number of years..

Not bad, just about stop the casual user, but if I really wanted your info the hard drive would be gone in less than 5 minutes, unless you have it locked in a secure enclosure, at which point you just take case and all.

I was a PC tech from 95 -02 I only had a few PC's they user kept locked, It usually turned out that the guy with the locked computer had something grubby secret to hide.

I did use a lockable hard drive caddy from a Fujitsu machine as a hidden safe, my company removed to eliminate the change of some moron removing the drive, yes they where that dumb at times , I could tell some stories lol.
