Is this going to do any damage?

I'm trying to save space on my desk so have put my screen on top of my external dvd burner and have my hard drive on it's side.

Now before i power either up i'd like to know if this is going to do any damage. The dvd burner never realy gets used much so heat shouldnt be an issue.

Thanks

That should be just fine.

It should work, if you're worried, you can buy one of those shelves (I can't remember it's name) for the Mini that your disc drive should fit under.
