Do you know what sort of interface it uses? (IDE, SATA, ect?) A picture of the connector on the drive would be enough to tell by if you aren't certain.
If it's a SATA drive, you can pretty much hook it up just like any additional hard drive and the system will recognize it as an additional drive in windows explorer. If it's IDE, your best bet is to just buy a USB enclosure for $7 http://www.newegg.com/Product/Product.aspx?Item=N82E168... it takes less then two minutes to install the drive and have it recognized just like any other external disk.
Yeah, that'd work just fine too... really, any IDE to USB enclosure should work fine for your purpose. The mot expensive USB enclosure are intended mostly for people building permanent external storage drives. As long as it's 2.5" IDE, any model should work fine.
