Wow, that's a lapse in system design - that computer clearly needs an Abloy classic!
Also,
hard drive bays (those that could be swapped between computers) (before they invented USB drives) used to have tubular locks, too.
Often a combination of an electric switch that cut the power off when in 'open' psoition and a cam lock that blocked the drive in place in 'closed' position.
If you wanted to swap the drive, you had to use them.
Low security, though.
