Issues

 One of the capacitor from m1-atx was damaged and was causing weird issues on bootup of the system 
 --> Capacitor replaced and the system went back to normal.

 The initial installed cpu fan was too big leaving almost no space from the case ceiling, what was causing the cooling not to work properly 
 --> Replaced with a smaller fan.

 Ethernet card is not recognized and seems not to be working at all.

 Some errors regarding not shielded usb ports (causes the system to sometimes hang when connecting usb devices)
