I attached some feet, and the whole cabinet leans slightly backwards.
Secondly, I have a very heavy weight (PC, xbox, wii) all in the bottom.
It is so slim, the centre of gravity is actually on the back side, so super stable.
But, since I have little ones, I will be attaching it with a latch to the wall.
The reason for the slimness, is that it is in an duet-house (as in two houses on top of each other, I have the top house).
So limited space. I got the space in front of the prepaid electricity meter (the thing with the keypad) so really really space limited.
The cabinet actually had to be sized around these constraints.
And if you still have not guessed, still have some last finishes to do, as in the marquee, front panel, screen cover, painting, etc.
