hi all, just want to ask if the setup I have is ok or can cause future problems. I got 2 HD, western digitals, a 20G and an 80G, that are mounted on the case one ontop of the other....not touching, but very little space between them. It is the layout of my case that I can't do much with it. I am just wondering if this setup will damage the drives? do need to spend money and get a new case to have better air flow? any advice would be appriciated
