plastic is not hard enough, or very brittle and easy to crack, the quality is certainly a problem. Steel plate should be at least 0.8 mm or more, (good chassis steel plate
thickness of 1 mm or more) the material should be galvanized steel, hardness and elasticity of strong, if the thickness is not enough or a little bit of force can be bending is certainly not
is a good material. Secondly, look at the workmanship. A look at the steel frame whether there is a burr, sharp mouth, good chassis are often wrapped, at least after polishing
treatment, will not let you in the installation of the machine "bruises"; look at the chassis frame is solid and stable, the easiest way is to lift up and shake
shake, if there is a shaking or even deformation, certainly not a good product; third look at the frame of the chassis is solid and stable, the simplest way is to lift up and shake
shake, if there is a shaking or even deformation, it is not a good product. The most important thing to remember is that if you're looking for a good deal, you're going to want to look at the interior of the chassis to see if it's a professional one. Then look at the front panel can not be extended, there are many Internet cafe special
chassis in the front panel is no optical drive slot.
