[quote name='specialk']how much do the external casings run, munch?
i'm also assuming the include the usb hookups (dumb question)?[/QUOTE]
Yeah, they include the hookups. external casings can go anywhere from $20 to $60, depending on what you want. The more expensive ones include a fan, which is a must if you're hooking up a HD. I don't think it's as bad for a DVD writer. It kind of cools itself witht the disc spinning creating air. You would also open it a lot, which would cool it. But if you're getting a HD, get one with a fan!
