If they really wanted to, couldnt they open the case, (I assume the case itself only has the regular thumbscrews and no lock) break the connection behind the wires and touch them together? seems like a system that isnt quite finished..

I've heard people refer to the whole box as the CPU. Using your car analogy, I think its along the same lines of people calling a car a "motor" (as in motor car). Also, as calling the computer a CPU is generally a marketing thing, it may originate from buyers assuming that a computer includes a monitor, keyboard, etc., and being miffed when they only receive the box and nothing else.

I'm 51 years old and have been all over the country and I have never heard a single person in my life call a car "a motor." I repair and build computers and read all the marketing stuff and I have never seen any company selling computers who refer to their computers in their marketing as a CPU. That doesn't even make any sense.
Any company who wants to get people to buy their computers would not want people to read or listen to their marketing and have people think that they don't know anything about their product. Because if they refer to their computer system as a CPU, then it would indicate that they really do not have any idea what they're writing about in their marketing. I'm not nitpicking here, the computer as in the whole tower containing the components is not called a CPU. And whoever refers to a car as a motor is saying something down right bazaar.

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

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..

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.
