Unfortunately, the PC built part was broken on one of the staple holder, whereby the ventilation cooler not abutted right and failures of the PC wg. Overheating of the CPU came. I was glad not to get a spare part for the older Medion / Fujitsu motherboard. When Einabu I recommend expanding the power supply. At the screw you just go up fast. On the Internet, I have found an installation manual in a forum. There, the film is to be separated from the aluminum plate. Have I made nicnt since then the bare metal on the circuit board is present (was not removed in the original).
