The assembly instructions are adhered directly to the envelope. Since this is destroyed during the opening of the package, a scanner / smartphone etc. definitely should be available. The instructions (instructions), which is available only in English, describes the assembly reasonably accurate but not precise enough so that when one superimposes the individual layers while * not * the orientation (numbers up) observed the cutout for the Power supply is too small, ie the power plug is not in contact. The case itself is very flat, if necessary, I can not judge find heatsink place, but I do not suppose it. The small overall height air circulation is hardly possible, ie for Dauerbtrieb is this case, in my opinion, not suitable.
