We had a break in recently where someone tried to do a smash and grab. They got into the classroom and tried to take the Dell OptiPlex 745 that’s mounted onto the monitor but couldn't as all the cables were tangled underneath the desk.
Obviously if they had spent time disconnecting everything they would have made off with it, but with the alarm ringing they decided to leave it.
Tangled Cables FTW.
We've just started mounting PC's under desks in cages, this was done to stop vandalism and prevent RAM being stolen. Any PC's that haven't been put under desks have had security screws fitted to make access to the inside not as easy. Not had any problems of over heating or cables at the PC end being unplugged yet.
We use Kensington Twin Locks. Lock one onto the monitor, one onto the case / tower (prevents opening of the case on all of our HP's).
In most cases this is through the desk (where all the cables surface) so you would have to take the table with you :)
About £25-27/unit and we have a set of master keys that work for the whole site.
we had problems with overheating using this methods, but this was down to badly designed case/airflow in the computer start with, which was made worse by the only badly situated vents being completely covered by the metal cage!

As far as the cables are concerned, there are plenty of inexpensive options on the market to prevent tampering & theft, such as locking network cables, locking VGA adapters etc, costing little more than a couple of quid each.
General rule of thumb is that if somebody wants something badly enough, they will get it no matter what deterrents are in place.
There are a few schools that I deal with regularly that have problems with theft of keyboards, mice etc. I generally advise them to buy cheap keyboards & mice as these are less attractive to the thief, and hold a couple of spares. For example, one of the schools I deal with buys all HP kit. Rather than HP keyboards & mice costing around £12 each, I tend to supply them with Logitech OEM keyboards & mice at around £3-£4 each. They are decent quality & do exactly the same job as the HP ones, but for some reason, tend not to go walkies as often as the HP ones.
