A flight case with a padlock should do you allright.. but doing something like a motorcycle chain through one of the carry handles securing it to your bed wouldnt hurt either or somewhere else highly immobile in the room.

Just be cautious of locking them up. Truth be told id be more worried about being known as a DJ in your dorm. For the simple fact Dj=CDs. I would worry ALOT more that your CDs/Vynals are stashed, sorted, catalouged and accounted for. THat way things dont go missing while you were at class and the roomate has "no idea what happened to them"
