Locking a PS3 (Literally)

Hey guys, im new here, but i have a quick random question.. im at college and have a ps3.. my roomates have sketchy people over and i dont really trust my ps3 around them.. so other than just taking it home, is there a way to physically lock a ps3 to something so that it cant be physically removed from its location ? (similar to locking a laptop to a desk..)

Thanks Guys!
