set it up where ever it makes you feel comfortable and can be undisturbed. I have one that is currently in the loungeroom, but wont be there much longer and will be put somewhere safer
I also have my cards and rune stones in my glory box. it is closed and (was until recently) locked (i lost the key =P and had to break the lock to get into it..) but they are safe, and i just have to open the lid to see them all spread out etc..
