How to recognize the good and bad used chassis?

First look at the material. Good chassis front panel of the plastic are used is made of ABS engineering plastic, strong and stable. If the chassis used

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.
