You have to insulate the metal case is you are just laying the board in say a tin. You can line the bottom with electrical tape. I would probably do a two layers of electrical tape myself. The bottom of the board can have sharp points if the part leads are not cut down enough and they could make their way though the tape. Some people use a piece of thick plastic as their insulation. You can get some really thick tape similar to electrical tape but a few times as thick if you have nothing else around.
