Modding server 1U

  
   Servers of famous manufacturers have perfectly figured out aerodynamics… In a word, all air currents within the server case are thoroughly thought over in order to avoid blind zones and other difficulties with cooling so that even the weakest radioelement can get proper cooling.
I mark the spots for back slots, provide space for power box. I drill holes in all vacant space for better air circulation.
 

   It’s an awfully routine and tedious job. Iron is thin, you have to drill in three stages and then bevel the workpiece. It’s handy to do the drilling on a steel support, this helps to keep even edges. I advise you to use spotfacer for beveling. Beveling with a drill is not so handy but is also possible on steel support.

   All edges and faces must be processed carefully. A tiny cutting inside the server can damage it… To keep save from such problems, the quality of beveling must be perfect, the finished case will be multiply cleaned out by compressed air and washed, the joints will be coated with varnish.
    

   Thus, the back wall is finished and mounted to its place. Now it’s high time to fit the mother board. I’ve cut out such a plate from an old computer casing to make reinforce our case and fix the power unit.
