Welcome aboard Anders.
Be prepared to to fix faulty keyswitches.
From memory, the front bezel is for Hitachi drives.
Later revisions had the disk drive cutouts changed later to accommodate other brands of disk drives such as Mitsubishi.
Be careful when servicing the power supply. It uses mains voltages.
The capacitors tend to dry out and their capacitance decrease.
All the power supply does is provide +12V and +5V for the disk drives, and +10Vish for the microbee often using a diode bridge to drop the voltage and make a small heater.
Skol!
