Budget business PCs that run Vista - Article Example

Although all three systems are comparable to their performance and business class features, yet Dell OptiPlex 740, with 2.2 GHz Athlon 64X2 processor, 160GB Hard drive capacity, superior mini-tower case design with horizontal orientation and super quiet operation has advantage over the HP Compaq dc 5750 and the Lenovo 3000J115. The ultra compact PotiPlex 740 can be mounted at the back of 17 inch LCD monitor. The OptiPlex’s hard drive has been installed perpendicular to casing in plastic sleds with rubber mounts to avoid the vibration.

Slot cuts are made into the interior of OptiPlex 740’s case to mount the optical drives without screws. The expansion cards can also be installed by a quick-release adapter. The OptiPlex’s also has a superior cooling system. The Dell uses a 5-inch-diameter slow turning fan to pull air through an even bigger plastic shroud which is mounted over a massive CPU heat sink. A 3-inch fan is mounted at the back of case and an inward cooling fan for power supply cooling is provided hence  across air ventilation arrangement is made.

Compare to Dell OptiPlex, HP and Lenovo PCs use the traditional cooling setup with two fans- one in the power supply, located against the back of the case and one mounted on the top of CPU’s heat sink. The HP Compac dc 750 has micro tower configuration with same 2.2 GHz Athlon 64X2 processor and 160GB HDD. HP too have utilized the same quick release mechanism yet it is not as good as OptiPlex.The expansion slots retainer, for example, is a metal piece held in place by the case lid and if we remove the lid, the retainer can rattle around.
