Just remember that if you put a rug or something on the floor, it needs to be the kind that 'breaths' (in other words, the bottom of the rug shouldn't be that solid rubber, nonskid stuff). Otherwise, humidity will get trapped under the rug causing it to be slightly wet.
I would suggest what the other person said, which was line the inside of the stand in a way that spills will be contained, etc. When doing general work on the tank, just always have some towels to catch small drips here and there.
