The choice of computer form factor should be considered in respect
to both the aesthetics of the space and the possible negative impact
of locating the base unit and security cage under the desk. Large
form computer base units located under desks can impinge on
leg room when there is a single user but also discourages student
collaboration and co-working where two students attempt to sit at a
single computer.
Historically the life expectancy of the computer base units was
dictated both by the expected electronic reliability/length of warranty
support and the period for which the performance of the processor
is considered acceptably current and is able to support current
software requirements. Typically this has been less than five years.
Since the introduction of widescreen LCD monitors there has
been little in the way of evolution of monitors. Now that many LCD
monitors have LED backlighting the life expectancy should be
greater than previous generations (which tended to go dim after four
or five years).
Given the life expectancy of the computer base unit and monitor
are comparable now preference should be given to the adoption of
‘all-in-one’ form factor computers. Typically these provide a cleaner
look, with less cabling to conceal (or fail) and are significantly more
energy efficient.
All-in-one computers should be installed by mounting them to the
desk on an adjustable, spring-balanced, arm with security fixings to
prevent unauthorised removal.
