Best blackboards: At Fermilab, every office has at least one that stretches from the floor to the ceiling.

I found it inconvenient that the whiteboard space was also used for magnets (to hold paper), the whiteboard marker holder, and the eraser (has a magnet so it stays on the whiteboard). The magnets were easily removed — if I need to put something on the whiteboard, I’ll just take them out again. But the holder for whiteboard markers and the eraser have to be near the whiteboard.
So, I drilled a hole into the holder (using a drill for metal), put a nail though it and nailed it on the wall. This left only the eraser, but given that it has a magnet inside, I only needed a metal area. Luckily, the cheapest coin in Germany is magnetic. Glueing two on the holder (and putting some scotch tape over it to protect the eraser) worked well.
End result: The whole whiteboard can now be used.
