I got a bunch of parts delivered today for the new computer I'm building. One of these was the great Lian-Li PC60+USB aluminum case. A while back when I read the review of the case I had no idea that the case that I ordered would in fact come with a rack on the bottom that would hold 4 or 5 hard drives, but they all have to be mounted sideways. This is different from the case that I saw in a review. Unfortunately, no hdd can go in the second rack (where the floppy is) unless I take a slot cover off. Is it safe to mount a hdd sideways on that bottom rack?
