Hello, I'm currently using a computer using a retail HP case. There is currently only room for one Hard disk drive however HP says you can install a second hard drive on the bottom of the case where they have screws so you can attach it. However I have installed a newer graphics card that generates much more heat and I was just wondering if you guys think it's a good idea to install a Hard Disk Drive on the bottom of the case. I'm currently still searching for a new case. I'm a little anal about how it looks on the outside. So I was wondering if I should either wait for my new case or just stick it on the bottom?
