New
PC's that you either buy or build now will use an ATX
type case. This has a pre cut plate to accept the motherboards
I/O connections. This saves in the main the use of back
panel blanking plates.
19"
Server style cases, will be of a very robust construction
and made of heavy gauge metal. They are designed and
built to last a lifetime. They are generally measured
in units called a "U" this is equal to 1"
A 4U will therefore be 4" in height.
These type of cases will also often have a lockable
front panel cover to prevent a person from tampering
with the system. They would generally be mounted in
a 19" rack cabinet with other equipment.
