i just buit a 960 GB file server for work 8 120GB hard drives with dual xeons and four case fans that thing sound like a lawnmower when you start it up i put in a sweet ass raid card that supports 3 seprate raid configurations the only downfall is that after designating one drive as the system drive then mirroring that drive then setting up the other 6 drives in a raid 5 im down to only 600 GB of usable storage space
