I do not know yet.
Besides, I do not know English well.
I thought to put mdf, but it is reflected in the mirror, not black. -
An important step is to choose a good mirror. Thats step one. Knowing its transmission is important to the lightlevel of the place where the mirror will be located. This means how much light comes from the monitor through the mirror and is visible for example in you bathroom. A lot of german users recommend this product:

You can set your own size.
The backside of the mirror can be mdf, but it should be painted black. This raises the mirror effect and no light shines through. You can also build a small frame and spray the uncovered parts black.
For glueing you can use mirror glueing tape or a hot glue gun. This results are most stable. Glass weights a lot.Be aware of the right ventilation for your pi. Otherwise its getting too hot, even if you use a fan.
Hope I could help a bit. -

I am going to drill three holes of 2cm on both sides.
Do you have tips on ventilation?
Thank you! -
Drill holes in the top and in the bottom for a chimney effect. Heat goes always upwards.
