| Casing:
Casing is mainly concerned with the power cords and the power supply. Power unit: The power unit is like any AC-DC current converters, the power output varies from 200 watt to 350 watt and above. Voltage: There are various voltage output, for the CPU, the voltage is typically 2.0 volts and for the small led bulbs, the voltage is almost negligible because of small power consumption. Connectors: The power connectors for hard disk drive, floppy drive and CD-ROM drive are all female four hole connectors, The data link between the hard disk drive and the main-board is 40 hole female connectors. This is true for the CD-ROM drive and floppy drive as well.
