"Dell’s build quality is particularly good as the SC440 is enclosed in a
solid steel shell which is the same as that employed by the higher-end
PowerEdge SC1430. There’s room at the front for a pair of 5.25in devices
and the price includes an IDE DVD-ROM drive. The system doesn’t have any
PS/2 ports but does come as standard with the appropriate keyboard and
mouse. To access the interior a large lever at the back is pushed
forward which pops the side panel out for easy removal. The lever itself
can be padlocked shut to protect against wandering fingers."
