I have this case, http://www.nzxt.com/products/tempest/ , and the HDD screwless drive rails seem really loose. I tried to invert the case just our of curiosity and the hard drive began sliding out. While I know this isnt, every day operation, I don't want the hard drive sliding around if I do have to transport the computer or most importantly, dont what the hard drive vibrating inside the case making all kinds of noise.
