It depends what kind of hard drives those 10 are.
You need to know the interface of the hard drive (IDE, SATA, SCSI, etc).
Also, what is the size of the hard drive? Not capacity but the dimensions of the hard drive. If they are laptop IDE hard drives, you can use this enclosure. http://www.esaitech.com/commerce/ccp98124-apower-enap25u-2-5--usb-2-0-hard-drive-enclosure---enap25u-1182575.htm
Works out pretty cheap and it is easy to change the drives.
