Will a PS3 Slim sit on top of a xbox 360?

Ill be grabbing a PS3 Slim soon but i have space issues (university dorms = blah for space :( ) so im wondering if I can place it on top of my 360 with out it falling off or causing overheating?

Yes, but don't, and you should probably move this to either System Wars or the Slim sticky

Thanks for all the help guys!
