Hello, Has anybody here tried removing their MBP's Superdrive i.e. DVD+-RW? I'd be interested to know how much it weighs and how much power it uses when not actually in use. Even with no disc in it, it does rev up from time to time when I do an Open... file. I know I can replace it with a hard drive bay, but I don't especially need that. I'm contemplating just leaving it empty. But it might be nice to some day add a second SSD. Thanks.
