I was watching a review on the R4 and saw you can attach 2.5" drives behind the motherboard. I have a 320gb laptop hdd. Could I mount this drive back there as well or does a hdd have to be mounted horizontal? It would be nice to have the front with the hdd mount removed.
If you have the hard drive already then go for it but the vibration might not be good for the drive so if the mount has rubber screw mounting system than thats better.
Hope it helped!
I'll look into some rubber pads for it. Just worried it might get too hot.
