How many 1" hard drives can you fit in an ordinary computer bay?

[rhofland at localnet.com (Randall Hofland)]

Derek has made the point that 4 notebook drives would make a RAID 5 
feasible, and that is something that would fit within a CD bay, wouldn't 
it? The primary fault with the small drives is overall speed, followed 
by higher cost per unit memory. Finally, to make this work in Linux or 
BSD, you'd need a good chipset driving a hardware RAID system, and not 
rely on the primary box for that like so many of the cheap RAID cards a 
few years back that worked only under WinDoze SoftRAID.
