Epson Endeavor - Manual (Page 76)

Your computer may have a hard disk drive already installed in
the vertical drive bay. If not, you can install one hard disk drive
in this bay.
It is best to install your computer’s first hard disk drive in the
vertical drive bay. If you add a second hard disk drive or
diskette drive, use the lower horizontal drive bay.
