See the Internet cafe in question has bars in front, more like you have a business where the customer and one who enters his trade the grid will not work.

You presiza have the creativity and thinking that only protect the entrance will not protect your PCs, embedded PCs leave or create an embedded cpu will hamper the more difficult it is for the attempted robbery more likely you will have security.

There are several ways you can embed the cpu bench, some screws to hold the cpu this can also be a better idea if a sugeito think of assaulting his lan house and upon arriving he sees that the cpus are stuck it may not want to lose travel and try another action.
