So, if you somehow ran out of bays, and didn't really want to remove anything or get a new case, what's the cheapest way to add a new, external hard drive? The USB and firewire drives seem about $100 more than their internal counterparts, and I've seen external casings for hard drives for around $50... Are they found cheaper, anywhere? I don't really care about size or power requirements or looks or anything... Firewire would be nice though USB 2.0 is alright too, but cheaper is definately a plus.
